I can not do much for you. just take some values of x like - 90,-60, - 45, -30, 0 , 30, 45 etc and do your graphs
Excellent graphing help can be had at

For your example, I'd enter two functions:
cos(2x*pi/180)
-sin(x*pi/180)
and set the x range from -100 to 100
and set the y range from -1 to 1
The pi/180 factor is needed because it plots the angle in radians, not degrees.
