Degrees to radians

The  exercise appears under the Trigonometry Math Mission. The objective of this exercise is to help users learn how to convert an angle in degrees to radians

Types of Problems
There is one type of problem that shows up in this exercise:
 * 1) Convert angle angle in degrees to radians - An angle in degrees is given and the student is required to convert in to radians in terms of pi.

Strategies

 * 1) There are 360o in a circle as well as 2pi radians in a circle. So there are pi radians in 180o. So we can convert an angle from degrees to radians by multiplying by it by pi and dividing by 180o which is $$xo times pi/180o$$
 * 2) For example, in the example given above, we multiply 300o by pi and divide it by 180 which gives us 300pi/180 which is 5pi/3 radians simplified.
 * 3) An ability to simplify large fractions quicky will help in achieving speed badges in this exercise.

Real-life Applications of Radians

 * 1) The radian  is the standard unit of angular measure, used in many areas of mathematics.
 * 2) An angle's  measurement in radians is numerically equal to the length of a corresponding arc of a unit circle
 * 3) The radian is widely used in physics  when angular measurements are required. For example, angular velocity  is measured in radians per second  (rad/s)
