COMPUTING THE VOLUME OF SOLIDS

Often, students work with shapes and solids under Geometry. Geometry deals with the study of solids and shapes and the measurements associated with them. Therefore various calculations with respect to the size, shape and volume is often done under Geometry. One of such computations is calculating volume of solids.
There are various types of solids. They are:

  • Cube
  • Cuboid
  • Prism
  • Pyramid
  • Cylinder
  • Sphere
  • Cone
Students can use various volume formulas to calculate the volume of the various solids. The Volume is basically the 3 dimensional 'space' occupied by a particular solid.

Students can solve problems on finding volume. Ample problems are available online for students to practice upon. They can also get Geometry tutoring online to get help with solving problems in geometry.

Double integral

Introduction to double integral:Let us consider a single valued function f(x, y) of two independent variables x and y defined in a closed region R of the x, y plane. Divide the region R into n sub regions ΔR1, ΔR2, .... ΔRn by drawing lines parallel to the axes of coordinates. 

For solving problems on double integral,you will need to know the integrals formula.


Double integral polar co-ordinates: In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a fixed point and an angle from a fixed direction.

Analytical Geometry

 Analytic geometry is the study of geometry using a coordinate system and the principles of algebra and analysis.It is also known as co-ordinate geometry or cartesian geometry.

Usually the Cartesian coordinate system is applied to manipulate equations for planes, straight lines, and square often in two and sometimes in three dimensions of measurement .

Analytical geometry basics
Points, Straight lines, Planes, Second-order curves and Surfaces are the basics of analytical geometry.

Straight lines are  formed when minimum of two points is joined with a constant direction.Planes are formed by two dimensional surface.The dimensional surface is formed by infinite number of points. Analytical geometry is concerned with all kinds of surfaces and curves like conic section.

Pre algebra

Pre-algebra is a course in Math .It is generally taught to students in the 7th and 8th standard.Pre-algebra is taught to students as a preparation for learning algebra.

Pre-algebra includes learning about natural numbers, integers, fractions, decimals, factorization of natural numbers, etc.

You can get pre-algebra help online.You can avail online tutors at home by sitting in front of PC.

Pre- Algebra requires a clear understanding of concepts and  high school Algebra is based on it.

Graph Theory

In Graph Theory, a graph is an accumulation of dots that may or may not be joined to  each  other by lines. It doesn't amount how big the dots are, how long the curves are, or whether the curve are straight, curved, or squiggly. The "dots" needs not to be round! 

All that matters is which dots are joined by which lines.
Two dots can alone be affiliated by one line. If two dots are joined by a line, it's not "legal" to draw another line joining them, even if that line stretches far  from the first one
 Graph theory applications: Graph theory  plays an important role in the design, analysis, and testing of computer programs. It is important for the fact that flow of control and flow of data for any program can be expressed in terms of directed graphs.

Geometry constructions

Construction of geometry involves drawing of shapes.In construction, we use compass and scale. 

Geometry construction rotation: Circling is the movement (turning) of an object about a point through a given  number of degrees in a clockwise or an anticlockwise. A two-dimensional object rotates in the adjustment of a center most or position of rotation.


Example of construction of geometry:
Construction of parallelogram type of quadrilateral is AB = 11 cm, BC = 10 cm and ÐA = 60o
Solution:
First we can draw AB - 11 cm and make  ÐA = 60o
Then cut the line AD - 10 cm ( accordingly AD = BC)With B as center and a radius 10 cm, draw one arc and with D as center and radius11 cm cut that arc at C.
Join the line BC and DC.Then ABCD is the construction of appropriate parallelogram.

Matrices

What are matrices?
    A rectangular array of entries is called a Matrix. The entries may be real, complex or functions. The entries are also called as the elements of the matrix. The rectangular arrangement of entries are enclosed by bracket or by square bracket.

You can also check the link on matrices determinants and determinants of matrices.

There are different types of matrices -  Row Matrix, Column Matrix, Square Matrix, Diagonal Matrix, Scalar Matrix, Identity or Unit Matrix, Null Matrix or Zero Matrix

Operation on matrices:
Equality of Matrices, Addition of Matrices, Matrix Addition is commutative, Matrix addition is associative, Subtraction of Matrices, Multiplication of a matrix by a scalar, Multiplication of Matrices, Properties of Matrix Multiplication, Transpose of a Matrix, Properties of Transpose, Symmetric Matrix, Skew-Symmetric Matrix, Properties of Symmetric and Skew Symmetric Matrices,

Application of matrices:Matrices are applied on Homogeneous Equations (Constant = 0), Non Homogenous Equations.

Mathematical Induction

Mathematical Induction:It is a technique for proving a statement, a theorem, or a formula that is asserted about every natural number.

Before we take an example on mathematical induction I would also like to provide you a link on Mathematical reasoning

Example of mathematical induction:
Mathematical induction is used to prove that the following statement holds for all natural numbers n.
0 + 1 + 2 + \cdots + n = \frac{n(n + 1)}{2}\,
Let us call the statement as P(n)
Show that the statement holds for n = 0.
P(0) amounts to the statement:
0 = \frac{0\cdot(0 + 1)}{2}\,.
On the left-hand side of the equation, 0 is the only term, and so the left-hand side is equal to 0.
On the right-hand side of the equation, 0·(0 + 1)/2 = 0.
The two sides are equal, so the statement is true for n = 0. So, it has been shown that P(0) holds.
Inductive step: Prove that  if P(n) holds, then  P(n + 1) also holds.
Imagine P(n) holds (for some unspecific value of n). It must  be proved that P(n + 1) holds, i.e,
(0 + 1 + 2 + \cdots + n )+ (n+1) = \frac{(n+1)((n+1) + 1)}{2}
According to the induction hypothesis that P(n) holds, we can rewrite  the left-hand side as follows:
\frac{n(n + 1)}{2} + (n+1)\,.
Algebraically:
\begin{align}
\frac{n(n + 1)}{2} + (n+1) & = \frac {n(n+1)+2(n+1)} 2 \\
& = \frac{(n+1)(n+2)}{2} \\
& = \frac{(n+1)((n+1) + 1)}{2}.
\end{align}
Hence P(n + 1) holds.
We have proved both the  basis and the inductive step, therefore,it has been proved by mathematical induction that P(n) holds for all natural n

Prime number theorem

Statement of the prime number theory:

Let π(x) be the prime - counting function that gives the cardinal of primes which is less than or equal to x, for any absolute cardinal x. For example, π(10) = 4 because 2, 3, 5 and 7 are prime numbers which are less than or equal to 10.
According to prime number theorem,the limit of the quotient of the two functions π(x) and x / ln(x) as x approaches infinity is 1, which is expressed by the formula:
\lim_{x\to\infty}\frac{\pi(x)}{x/\ln(x)}=1,
Using asymptotic notation the above formula can be written as
\pi(x)\sim\frac{x}{\ln x}. 
The theorem states that x/ln(x) approximates π(x) which means that the relative error of this approximation approaches 0 as x approaches infinity.
See the link for Prime and composite numbers
An example of the problem on prime number theory is given below: 
 
Solution:

What is a fraction?
A fraction is a part of a whole.A fraction is represented by a number having numerator and denominator.For example, 2/8 is a fraction.

How to divide fractions?
Suppose (3/4)/(4/2) is given ,
Convert the divisor into multiplication and invert the denominator.Then we get,

3/4 x 2/4 = 6/16 = 3/8.

How to add fractions? Fractions can be added by following the steps given below:
1)Make sure that the denominators are same.
2)Add the numerators
3)Put the answer on the same denominators and simplify if needed.

Adding fractions example: Let 1/4 + 2/4 be the given for addition.
According to the first step,since the denominators are same , the numerators will be added, we get
(1+2)/4 = 3/4
So the answer is 3/4.

understang the terms in circle

Basic terms of circles:

Center of the circle:In geometry circles, the fixed point , the fixed point is called the center of the circle.

Radius of a circle:The distance from the fixed point to any point on the circumference of the circle is called the radius.

Concentric circles:Concentric circles are circles drawn from a fixed point.

Chord: A chord is a line that is formed by joining two line of an arc.

Diameter: A diameter is a chord passing through the center of the circle.

I hope this basic terms will be of helpful ones.

Segment of a circle

Segment of a circle: When a chord divides the circle into two regions, the two regions are called circle segments.

There are major and minor segments.The major segment is the region bounded by the chord  and the major arc intercepted by the chord. The minor segment is the region bounded by the chord and the minor arc intercepted by the chord.

Circle segment area:The area of the segment of a circle is equal to the the area of the circular sector minus the area of the triangular portion.

The formula of the area of the circle segment is given as:

½ × ( (θ × π/180) - sin θ) × r2   (if θ is in degrees)
circular segment area 

Types of circle

A circle is the locus of all points which are at a fixed distance from a fixed point.There are two kinds of circles - tangent circle and intersecting circle.

Tangent circles: A tangent circle is a circle on which a line is drawn by touching at a point of the circumference of the circle.
Intersecting circles:When two circles intersect at two points it is called an intersecting circles.

Circle properties:1)Circles which have same radii are congruent
                           2)Equal circles have equal circumference.

There are many more properties of circles which we will discuss next time with diagrams.

Learn elementary statistics

What is statistics?
Statistics is the science of the collection, organization and interpretation of data.

Elementary statistics.
In the elementary statistics, you will learn the basic concepts in statistics such as the basic topics included in
statistics.Basic statistics include find the mean, mode and median.Here is an example of calculating the mean value.
Let us find the mean value of 4, 8, 2 and 10
First add the numbers as 4+8+2+10 = 24
Divide the value that you got by addition of the numbers by number of the numbers i.e, 4
Then, 24/4 = 6
So, the mean value is 6.

Next time we will learn how to find the mode and median.

Square number

Square of a number is the number that you get when you multiply a number with itself .For example, 16 is the square number of 4.

How to find the square of a number?
1)Take any number you want to square
2)Take the number before and after the number you have chosen to find its square
3)Multiply both the numbers that are before and after the number.
4)Add 1 to the number you got on multiplying.Now you will get the square of the number.

Suppose you want to find the square of the number 9
The number before 9 is 8 and the number after 9 is 10
Now, multiply 8 and 10.We know that 8 x 10 is 80
Add 1 to 80, then we get 81. So, 81 is the square of 9.

Hope you will find this article helpful.

In this article am going to discuss with you about random variables. If S is an representation space with a quantity reason and X is real valued meaning delimited above the principle of S, next X is known as random variables.. A random variable checkered is also called a quantity variable or a chance variable.
In probability learning random variables are used. They were formulated to help the games of alternative, stochastic actions, and outcome of specialised experiments.

To link between nubmbers and probability which we observed data the binomial random variable will help us.

The probability of distribution describes the range of a possible random value of a variable. Probability distribution in any two random variable identifies either each value of the variable or
value of the probability lying with in a continuous variable.

In mathematics there are two types of random variables, they are:
Continuous random variable and Discrete random variable.

Know about Perimeter:

Now am going to write about Perimeter. Let me first define perimeter. Perimeter is the sum of all the sides of a polygon shape.
There are different formulas to finding perimeter of different polygons.
Perimeter of Square:  In square all the sides are equal.
   So Perimeter = 4s
      where s = side length of the square.
Perimeter of a triangle:
In an irregular triangle, the perimeter is P = a + b + c.
Where a , b , and  c are the side lengths of the triangle.
  For an equilateral triangles Perimeter formula is given as  Perimeter = 3 s
 Where s = side length of the triangle.
Perimeter of Rectangle:
  In an regular rectangle opposite sides of the rectangle are always equal.
   Therefore perimeter is calculated using this formula: Perimeter =  2(l + b)
    where l = length and b = breadth of the rectangle.
This is all about perimeter formula for different polygons.

Know about Point-slope form.

Today an here to share my knowledge on point slope form and its equations. A linear equation is also an algebraic equation in which each term is either a number or the product of a number a single variable. straight-line equations is also called the Point-slope form.

To solve the problems on point slope formula we  need two points and slope and point slope equation. For this they give you  a slope m, a point (x1, y11) and have you plug it into this formula:
y– y1 =  m(x-x1)

You screw the generic “x” and generic “y” that are always in your equalization, and then you human the circumstantial x and y from the point they gave you; the specialized x and y are what is subscripted in the expression.

Various kinds of lines in geometry:

In geometry line is straight curve and it has no end points. Basically a line is formed by a set of points along a straight path , going to opposite direction. Usually lines are used to represent a straight object with negligible width and height.

There are usually three different types of lines in math. They are
  • Parallel lines : Two lines in a plane that are never meet are called as parallel lines. They are always the same distance apart. And also going to the same direction. Parallel lines have the same slope.

  • Perpendicular lines : Perpendicular lines are lines that are intersect each other at right angles. If two lines are perpendicular to each other then the product of their slope is equal to -1.

  • Intersecting lines : Intersecting line is the last one of the types of lines in math, where 2 or more lines are meet or intersect at a common point.
These all are about different types of lines in math.

Polynomials factirization:

Today i am exploring polynomials factorization. I will talk about factorization of polynomials basically. I hope you will enjoy this learning. In mathematics, polynomial is an expression of finite length constructed from variables and constants using only the operations of addition, subtraction, multiplication and non-negative, whole number exponents.

There is polynomial factoring calculator through which we can get the factors of polynomials. Other than that there are various methods of factorizing polynomials. Using this calculator you can easily solve math problem. The following are the few:

   1. Factorization by dividing the expression by the HCF of the terms of the given expression.
   2. Factorization by grouping the terms of the expression.
   3. Factorization using identities.


These are the methods of factorizing polynomials. Further we will move on to other concepts of math.

Learning on grade 3rd math

Let me give you some learning on the basics operations of fractions. This learning comes under the study of grade 3 math. Let us start with adding and subtracting fractions.
You can easily add or subtract like fractions means simply add or subtract the numerators and write the sum over the common denominator. For dealing with fraction problems you can also get help from online fraction calculator.
But before adding or subtracting unlike fractions you must find equivalent fraction with the same denominator like this:

First find the smallest multiple of both numbers and then rewrite the fractions as equivalent fraction with the LCM as the denominator.
When dealing with the fractions LCM is nothing but the Least Common denominator.
Some Adding fractions example:
4/8 + 2/8 = 6/8
5/10 + 8/10 = 13/10.
Adding and subtracting fraction with different denominator:
5/4 + 2/3
First convert each fraction into an equivalent fraction with the same denominator
12 be the equivalent denominator for 3 and 4
So (5*3 )/12 + (2*4)/12 = 15/12 + 8/12 = 23/12
In the same way subtracting fraction too.

The roster technique in math is called as tabular technique. In roster method a set{} which denotes the set of data’s & by listing all the elements of the set, that elements will be separated by commas like {1,2,5} A set containing 8,4,6,3,11,8 is Written as {8,4,6,3,11,8} in Roster technique.

In roster method there are two types:
Roster method
builder method

 The roster technique of math is the list or diagram of the ordered elements, when the rule is the equivalent form which will be using the choice of elements from a domain matching a rule.

Know about dimensional analysis calculator

Earlier I have given you some learning on solve for x calculator. Today I will tell you something about dimensional analysis calculator. So let us start learning .

 The dimensional analysis and its applications of a physical quantity are the powers raised to essential units in order to receive the derived unit of that physical quantity. Though the dimensional method is convenient to find the exact dependence of a physical quantity on other physical quantity.we can also see about topic dimensional analysis and it application. You can easily solve this dimensional analysis using dimensional analysis calculator.

Three dimensional analysis consist of two axes such as x,y and z with.The centre of the axes will be the origin.For spherical coordinates graph learning, they must find the coordinates and parameters.Sphere polar coordinates are also called as spherical polar coordinates and it is a two dimensional coordinates space.In this editorial they are going to learn about two dimensional analysis.

Index term, radicand term & the radical symbol is used for the evaluating the radical form. For example, is given as example for radical form. This editorial gives brief explanation about the definition of radical form with sample example issues.

Learn College algebra online:

Now start learning with college algebra. An additional document introduced that conference makes apparent, College Algebra is the earlier arithmetic coursework. College algebra preponderance may go in to to the classroom have already determined that it will be their concluding arithmetic. Topical data’s restricted in the first round document of a MAA Task Force, point to that merely single in ten College Algebra (CA) students go on to take a full length calculus sequence.

Online study helps you to be trained then & there when ever you need help in any topics. Math tutors will also help you regarding to your any queries.  This is most fascinating & interacting than books lecturing.


College Algebra can reside on its present path of a technique-driven program. In this case, techniques are accentuated & applications or issues are select that are vulnerable to the specific process. Information shows in this approach are unsuccessful in focusing students who have other choices or encouraging students to proceed on to calculus. College Algebra can create in to problem-based quantitative mathematics

Integers in math

In this blog am going to discuss with you about a mathematical concept what is a integer?
Any number which is not a fraction but can be negative, positive or a zero is an integer. Any numbers in a number line is an integer.  Example: -1,-2,-3,0,+1,+2,+3 etc. In order to work well integers you can also use integer calculator.
The addition, subtraction and multiplication of two integers also give an integer as a result. But in case of division it may result in an integer or a fraction also.
Example:
1)      When we add 3+4=7 i.e. we added two integers 3 and 4 it resulted in another integer 7.
2)      When we subtract 9-4=5 i.e. we subtract two integers 9 from four it resulted in another integer 5.
3)      When we multiply3*5=15 i.e. we multiplied two integers3 and 5 it resulted in another integer 15.
4)      When we divide 15/3=5 i.e. we divided 15 by 3 it resulted in another integer 5, but when we divide 5/10=1/2 i.e. we divided 5 by 10 it resulted in a fraction ½ .
In mathematical equations integers are generally represented with the help of alphabets like p, q, r etc

Here am trying to give information on free geometry help. I guess you liked my writing and also you are utilizing these. Further we learn about complex geometry problems.

Ratio and proportions:


Today Let us know about Ratios and proportions. Ratio and proportion is one of the most important concepts of math.. we today will discuss about ratio and later I will give you some knowledge on linear programing problems in statistics and probability. I will share with you how to find ratio.

A ratio is a fraction that is denominator and  numerator can have different units. Ratio examples : if you travel 100 miles in 2 hours, we can write that as a ratio:

 2hours
100miles
And we can simplify that ratio, using the selfsame techniques for simplifying fractions:

2hours100miles = 1hour50miles. Get more examples from solving math problems.

If a and b are two quantities with the similar units much that b is not equalized to nought; then the quotient a/b is called the ratio between a and b. It is handwritten as a:b.
Ratio does not bonk any object.
The quantities a and b are called damage of the ratio.
a' is called preexistent (early constituent)
b' is titled ensuant (gear constituent).


If there are 4 oranges and 5 apples, the ratios of oranges to apples is exposed as 2:3; where as the fraction of oranges to total fruit is [(4)/(5)].

Proportions: Four quantities a, b, c and d are said to be in equipoise, if a:b=c:d. a and d are titled extremes of the placement. b and c are titled effectuation of the arrangement.



Probability and Statistics:

Today I will give you some learning on probability and statistics. Which belongs to the branch of math(algebra). Let me first tell you what is probability. Furthe we will move on conditional probability and Ogive.

A probability tier chart is a table or plot, represent of the study charge of events. The construction interpret shows the chances an possibleness circumstance in place or time or state instrument decide abode turn from few combination of initial conditions.

An ogive is completely plotted and results in a two-dimensional or three-dimensional integer. Learning ogive is the primo utilized when you would same to demonstration the complete at any supposition container

The conditional measure of an event B in overlapping to an circumstance A is the chance that circumstance B happens specified that event A has already occurred. The writing for tentative chance is P(B|A), have as the measure of B relinquished A. this process comes from the procreation explanation and bit of algebra.

Amount storey represent is real light to interpret and compute the measurements. These are supported on straight and swimming alinement. This is relating to the flexile log alignment chip. Bit is denoted by set of the dates and frequency dates. By using internet you can also get math online help.

I guess you liked this piece of writing. Some other day we will move on different concepts of math.
