Polar Equation of a Circle - Definition, Coordinates & Examples

In plane geometry, polar coordinates usually involve a distance from a specific reference point denoted by r and an angle from a specific reference direction denoted by . The polar equation of a curve is written terms of these two variables. In fact every point on a polar co-ordinate plane is described by its distance from a reference centre and its angle from the reference direction. In general a polar coordinate plane would look as follows: In the above figure, the blue lines represent the angle measure with respect to the zero degrees line and the red circles represent the distance from the centre of the grid. The co-ordinates of that point would be written as (2,30). Consider a circle in a Cartesian plane as shown below: Note that the centre of the circle is at the origin (0,0) and the radius of the circle is r. For our example, (x_1,y_1 )=(0,0)and (x_2,y_2 )=(x,y) Also, Thus, Back to Top and.

Standard Deviation

It gives an idea of how the individual data in a data set is dispersed from the mean. Standard deviation is defined as the square root of the mean of the squares of the deviations of all the values of a series taken from the arithmetic mean. It is also known as the root mean square deviation. The symbol used for standard deviation is σ. 1. Prism - Different Types of Prisms. Discount Rates - How to Calculate Discount Rate?

How To Simplify Math Expression - simple math for students

Simplification means to write an expression in shortest possible form. Here, I will discuss few tips that must be kept in mind while simplifying a math expression. Simple Expression Simple expressions may consist of numbers and algebraic operators. 1) Order of Operations You must know the order to operations before trying to simplify an expression. 2) Solve Parenthesis First of all, you must solve if there are any parentheses.For example 3^2 + 5 – 2(3 + 2) – 10 Adding the numbers inside parenthesis, we get 3^2 + 5 – 2 x 5 – 10 3) Exponentiation After parenthesis, you must check for the exponents. 4) Multiplication Next step is to multiply if you see any multiplication sign in there.

Basic Probability Worksheet

Which alphabet is least likely to be picked? Solution: Number of times S and I occured in the word MISSISSIPPI is 4. Number of times M occured in the word MISSISSIPPI is 1. Number of times P occured in the word MISSISSIPPI is 2. The alphabet that is least likely to be picked is the one which occurs least number of times. So, alphabet which is least likely to be picked is M. Correct answer : (4) Shane's collection has 12 nickels, 24 pennies, 35 quarts and 45 dimes. Number of nickels in Shane's collection = 12.
