Calculus

You dont need infinities and calculus to do 3D graphics and video games.

that is, all the trigonometry you learned at school was a waste of your time, as it could be replaced with linear algebra.

Trig != Calc

Trig = Sin, Cos, Tan, etc...
Calc = Derivatives, Limits, etc...

And quite frankly if you don't understand basic geometry (Trigonometry is generally a part of a Geometry class and later part of a precalculus class, but never its own class), including the ratios of triangles sides, angles, etc... how the fuck do you think you're going to be programming a fuck ton of polygons?
