What I do is remember how sin and cos can be thought of as coming out of the unit sphere, with certain angles, and forming a right angle triangle from the angle, etc. Then you just have pythagoras' theorem.

you can actually prove it on any right-angled triangle by drawing it as follows: |dw:1353754910236:dw|

then use definition of sin(theta) and cos(theta) and pythagorus to prove it
