I've been doing a lot of opengl work in D. Opengl deals primarily

When using trigonometric functions, they all deal with radians. So

Actually, it isn't!
assert(sin(360 * PI / 180 ) == 0.0); // fails!
There are supposed to be sinPi(), cosPi(), tanPi() functions, but they
are not yet implemented (they are quite difficult to get right).
You should use:
sinPi(360/180); to get sine in degrees.
