Comments:
This is primarily feedback on Soner's comments. Actually, the trig functions *are* returning the correct values. They simply are not expecting degrees as input, but radians (2π radians = 360°). One rad thus equals approx. 57.2958 degrees (hence your division ratio). For most serious mathematics functions, you expect to use radians, not degrees. So it’s not an error, but you were missing the important knowledge of what was expected as input.
