The sin and cosine functions use angles as arguments and they return a value between +1.0 and -1.0. Most calculators either take degrees as the argument or can be changed from degrees to radians. The conversion is 360 degrees equals 2*pi radians. So to convert degrees to radians divide your argument (in degrees) by 360 and multiply by 2*pi. pi = 3.14159265 and 2*pi = 6.28318531.

As an example we'll convert 45 degrees to radians:

45 degrees / 360 = 0.125. Then 0.125 * 6.28318531 = 0.78539816 radians.
