COMPUTING PROBABILITY ON MATHS

Probability is an important topic in Math. It is important for students to understand the logic behind calculating probability and understanding the basics clearly. It will be easier for students to work problems under Math related to Probability thereon.
Probability means calculating the 'possibility' or the 'chances' of the occurrence of a particular or specific Event.
The Probability formula is given as the possibility of the occurrence of the particular event divided by the total number of possible outcomes .
P= P(E) / P(Total)
Example: Calculating the probability of the possibility of the occurrence of a Head when a coin is tossed once. It is given by
P(Heads) = 1/ 2
Where 2 gives the number of possible outcomes that is either Heads or Tail (1+1=2) .
Students can practice many problems which are available online. They can practice ample problems under Statistics which are related to computation of Probability.

SOLVING MATH EQUATIONS

Equations are an important topic under Algebra. Equations are those which have the a combination of expressions separated by an ' = ' sign.
Students often fumble with solving math equations. The methodology to learn and master solving equations is by understanding the logic involved and simultaneously practicing solving math problems on equations. Students can do so by observing solved examples on working with equations and attempting similar math problems.


There are different kinds of equations based on the exponential value or the 'power' to which the variables are raised to as:

• Linear equations
• Differential Equations
• Quadratic equations
• Radical equations
• Parabola and Hyperbola equations

There are ample number of online resources for students to learn and practice such problems under Algebra which deal with equations. They can also get online help with their homework Algebra problems making the learning process more easier.

Units of time

Unit of time: Unit of time is a unit of measuring time period.Second, minute and hour are units of time.

Second:

The second is the duration of 9 192 631 770 periods of the radiation which is corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.

Minute:

The minute is a unit of time equal to 1/60th of an hour or 60 seconds.A minute occasionally has 59 or 61 seconds; see leap second in the UTC scale of time. The minute is accepted for use with SI units.'min' is used as the symbol of minute.

Hour:

An hour is a unit of measurement of time of the duration of 60 minutes, or 3600 seconds.1/24 of a median Earth day is an hour. Time standard can also include a negative or positive leap second,and may therefore have a duration of 3599 or 3601seconds for adjustment purposes.

You can also check out the link on history of measurement.

Next time we will learn in details to know about the units of duration of time.

Conic sections

In Mathematics, a conic  is a curve obtained by intersecting a cone and a plane.There are three types of conics - ellipse, parabola and hyperbola.

The graph of a quadratic equation  in two variables is always a conic section in a cartesian coordinate system though it may be degenerate, and all conic sections arise in this way. The equation will be of the form
Ax^2 + Bxy + Cy^2 + Dx +Ey + F = 0 with A,B and C not all zero.

Conic section equation:If the focus is () and the directrix is ax+by+c=0 then the equation of the conic section whose eccentricity =e is given as
(x−)2+(y−)2=e2 .(ax + by + c)^2/(a^2 + b^2)

Tangent

Definition of tangent:

A tangent to a curve at a point is a straight line that touches the curve at that point.

Equation of the tangent to a curve:

y = mx + c

Example of tangent:

The line AB is a tangent to the circle at point P. 

 

A tangent line to a circle contains exactly one point of the circle.A tangent to a circle is at right angles to the radius of the circle at its point of contact.

  

Finding percentages

In mathematics, a percentage expresses a number as a fraction of 100.

How to calculate percentages?

To find the percentage that a single unit represents out of a whole of N units, divide 100% by N.In finding the percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. 

we have three important terms to define while finding  percentages:

Rate: The rate is the percent

Percentage: The result obtained when a number is multiplied by a percent

Base: The base is the total amount.

Dividing decimals

How to divide decimals?

To divide decimal numbers:

1)If the divisor is not a whole number, decimal point should be moved to the right to make it a whole number and move decimal point in dividend the same number of places.

2)Keep dividing until the answer terminates or repeats

3) Put decimal point directly above decimal point in the dividend. 

4)Multiply quotient by divisor and check if it is equal to dividend.

In free math help,  ‘divide’ means making a number into as many equal portions as possible or dividing the number into as many  equal portions as possible. It is opposite process of multiplication.

Permutations and Combinations

Definition of permutation and combination:Arrangement of things is called permutation.In the arrangement, the order is considered.Whereas, combination means selection of things in which order is not important.

Example of permutation and combination:

For example, we have to arrange a number that consists of three digits by using the given digits 1, 2, 3, 4.We will get different numbers according to the order of arrangement of the digits.This is an example of permutation.

If we have to form a team of 11 players out of 20 players,the order of players is not needed because order will not result in the change of the team.This is an example of combination.At least one player will have to be changed in order to form a different team.

Next time will learn about what is probability.

You can avail help on solving problems on permutations and combination as well from different websites.

Linear programming

What is linear programming?

Linear programing is the process of finding a way to obtain the best result in a give mathematical model for some list of requirements represented as linear equations.

Example of linear programming:
Consider the function D = 5x + 4y.We will find the minimum value of this function in the region defined by the inequalities x ≥ 0, y ≥ 0, x + 2y ≤ 4, and x + y ≤ 3.The possible region determined by the given constraints is shown.

 The vertices are (0,0), (3, 0), (2, 1), and (0, 2). In order to find the minimum and maximum value of D let us evaluate the value of D = 5x + 4y at each of the four vertices and we find that the minimum value of the function subject to the   constraints is 0.The process adopted in the example above is   called Linear Programming.See the link on solve linear programming

Least Common Multiples of 12 and 18

Types of Graph

Definition of graph: A graph is a representation of a set of objects which are connected by links.

There are different types of graphs:

1.Directed graph

2.Undirected graph

3.Mixed graph

4.Multigraph

5.Simple graph

6.Weighted graph

7.Half-edges, loose edges

Properties of graphs: 1.Two edges of a graph are said to be adjacent if they have a common vertex.

                                2. If a graph has only one vertex and there is no edges, the graph is called the trivial graph.

                                3. The graph having no vertices and edges is called the null graph.

                                4.The graph having vertices and no edge is called the edgeless graph.

Classes of graphs: Graphs are classified as : 1.regular graph

                                                                   2.complete graph

                                                                   3.Finite and infinite graph

2.Add the product of the two with the numerator of the fraction.
3.write the result that you get on the numerator and denominator will be the same.</sub>

Percentage

We can calculate percentage of any quantity by dividing the number by 100.calculation of percentage is used in our daily life whether it be business, offices or institutions.

In schools and college, percentage is used in assessing the marks acquired by students.

Let us see some example on how to calculate percentage.
Find 25percent of 80
     It is calculated as the following:
     (25/100)x 80
     =200/10
     =20
Hence 25 percent of 80 is 20.           
                                      
You may also be asked to find the percentage of 100kg of rotten potatoes out of 500kg.
Here you need to find how many percentage is rotten from 500kg if 100kg of potatoes are rotten.

Let's see how to calculate:
 (100/500)x100
  =100/5
  =20
Hence 20 percent of potatoes are rotten. 

Addition of fractions

Let us see learn how to add fractions by the following examples:
Example1.1/2+4/6
         = (3+4)/6)
         = 7/6
       
Example2.3/2+6/2+4/8
        =(12+24+4)/8
        = 40/8
        = 10/2


You can visit some websites where you can find questions on adding  fraction examples.You can practice at home to solve the problems.The answer for the questions will be provided  online.The method for adding fractions are also explained.

Distance formula

Distance may be defined as the measure of length from one point to another.The formulae of distance d between the points (x1,y1) and (x2,y2) is given as : d = square root of ((x2-x1)^2 + (y2-y1)^2)

Example: Suppose (-1,-2) and (-3,5) are the two points,then the distance d between the two points can be calculated by using the above formulae.Then we get , d = square root of ((-3-(-1))^2 + (5-(-2))^2 = sq.root of ((-3+1)^2 + (5+2)^2) = sq.root of ((-2)^2 + 7^2) = sq.root of 4 +49 = sq.root of 53.
There distance d between the two points = sq.root of 53.

Distance mid-point formula: According to the distance formula, (x1, y1) and (x2, y2) are the end points of the distance d.

The mid point distance formula is written as: ((x1+x2)/2)((y1+y2)/2)units.

Example of finding midpoints between two points:
Suppose if we are to find the mid-point of the two points (6,3) and (9,1).By using the mid-point formula ((x1+x2)/2)((y1+y2)/2)units, we can write as: ((6+9)/2)((3+1)/2) units = (15/2)(4/2) = 7.5 x 2 = 15 units.

Forms on linear Functions

A linear function is a polynomial function of first degree with one variable.The standard form of linear functions is written as f(x)= mx + b.

A linear function is represented in a cartesian plane by a straight line. 


Slope intercept form of a line:
y = mx +b is the slope intercept form of a line where x and y are coordinates of any point on the line,m is the slope of the line and b is the y-intercept.

Slope point-form of a linear function:

(y - y1) = m(x - x1) is the slope-form of a line.

Intercept form of a linear function:

(x/a)+(y/b) = 1 is the intercept form of a linear function.

Let us take an example on form of linear function.If a linear function is defined as 10x-5y+15=0, how to we express the function in slope-intercept form.
Soln.10x-5y+15=0
     or -5y=-10x-15
     or y=2x+3  
So, the slope intercept is y=2x+3.


Next time we will learn about differentiability of a function.
See more examples on how to write a linear function in different forms from free help on solved examples.

Vector

What is a vector?

A vector is a physical quantity which has a direction. Velocity and acceleration are examples of vector.

Types of vector:

Null vector or zero vector:A vector whose initial and terminal points are coincident is called a zero or null or a void vector.  a  = AB is the presentation of null vector.

Proper vector:Vectors other than the null vector are called proper vectors.

Unit vector:A type of  vector whose modulus is unity, is called a unit vector.

Negative of a vector:

  
The negative of a vector AB is a vector whose magnitude  is the same as that of vector AB but has the direction opposite to it.

Thus AB represents the vector of vectors a

= > BA represents −a

 

Learn calculus

The key concepts in calculus are integral calculus and differential calculus.

Differential calculus is concerned with the instantaneous rate of change of quantities with respect to other quantities, or more precisely, the local behaviour of functions. This can be illustrated by the slope  of a function's graph.Integral calculus studies the accumulation of quantities, such as areas under a curve  linear distance traveled, or volume  displaced.

Calculus help free is available on internet provided by experts.

Calculus has widespread application in areas like Engineering and Science. Since the study of Calculus is pivotal in branching out to other fields, it is important to get the best Calculus help right from the formative years itself.

Geometric sequence

A geometric series is a series with a constant ratio between successive terms. For example, the series

1/2+1/4+1/8+1/16+.......is geometric, because each term  except the first can be acquired by multiplying the  first term by 1/2.

 

Geometric sequence:

A arrangement in which each term after the first  is a constant multiple of the  preceding  term is a geometric sequence.For example, The sequence, 2, 6, 18, is geometric since the arrangement between two adjoining  terms is consistently 3. That is, each term multiplied by 3 will produce the next term.

The accepted term of a geometric sequence (an) with a first term of a1 and a common ratio of r is an = a1(r^n-1).

Polygon shapes:

Hi,

Now am going to write about polygons. All of you know that the different names of polygons. So today's learning is based on regular and irregular polygons. When anniversary ancillary and angles of any polygon are similar, again it is said to be a approved polygon.

                                                 
A approved polygon is one with its absolute abandon agnate and anniversary of its angles similar, for instance: A approved polygon with 3 surfaces is said to be boxlike triangle.

The regular polygons’ angle is grouped into two types. They are 

• Exterior angles : Regular Polygons’ Exterior angle = 360° / n   where n is the number of sides. 
• Interior angle : Angle of regular polygons = [(n - 2) / n] × 180°
            where n =number of sides.

When angles of the any polygon are not the same, again it is known as irregular polygon.

This is something about regular and irregular polygons. If you have any doubts or comments leave it here.

Some Math Formulas

Triangular Prism:

Triangular prism is a polyhedron of a triangular base. Triangular prism is a three dimensional with a solid base, 9 edges, 5 faces and 6 vertices.
                                                
Formula to find out the volume of a triangular prism is given below:
Volume = (1/2)*base*height*length.

You can calculate the Volume of the triangular prism using these simple steps:

1) Choose your unit of measurement.
2) First measure the length, height and base of the prism. Sometimes base is also called as width and Height is the altitude of a triangle and is perpendicular to the base.
3) Multiply the 3 dimension together. It does not matter the order in which you multiply the numbers.
4) Then divide that answer by 2.
5) Finally write your answer in the proper cubic unit of measurement.

Using this step you can easily calculate the volume of the triangular prism.

Some learning on 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 shapes.

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 triangle 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.

Square root calculator:

In last session I have given you some information on interval notation calculator. So today i have decided to give you some knowledge on square root calculator. In mathematics , a square root of a number x is a number r such that r² = x, or, in other words, a number r whose square is x. For positive x, the principal square root may even be written in exponent notation, as x1/2. For example, the  square root of 16 is 4, denoted sqrt (16) = 4², because 4 = 4 × 4 = 16 & 4 is non-negative.

Square root calculator is used to find the worth of the given square root term. In square root calculator they can post the square root term in the appropriate place given & then they must press the button "calculate". after that the result is given immediately. it is very simple to find the worth of the square root terms. then they must perform another value they must press the "Reset" button. now the values are cleared & able to perform the calculation. 

This is about square root calculator online. Next my writing will be on other different types of online calculators. Till then enjoy this piece of writing.

Know about interval notation calculator:

Today let us know about interval notation calculator. This editorial is about online calculator. Plenty of math issues are solved using math calculator. There's different types of online calculator. A quantity of the various online calculators are arithmetic calculator, calculus calculator, scientific calculator, differential calculator etc.

The net calculator helps to solve the issue quickly to receive the necessary answer. They can save time by working with online calculator. The tutors are there always to help the students in online calculator and you can also get math answers free online.

The interval notation denotes the set of actual datas with the property that any information that deception among in the set is also has in the set. For example, the group of all the datas x satisfying  0 ≤ x ≤1  this is an range which has 0 & 1, as well as all numerical values among 0 & 1. In this editorial they can speak about about preparation of interval notation.
