Angles...

How do i express angles in a radian measure as multiples of pi.
For example, suppose i have an angle of 30 degrees, and a angle of 270 degrees. How would I express them in a radian measure as a multiple of pi?.
Thanks.

180 degrees is pi radians.
That is all you have to remember.
For example to convert 30 degrees to radians:
30 degrees * ( pi radians / 180 degrees) = pi/6 radians
