I know that this question doesn't pertain to this board, but are their any good books for learning trigonometry/calculus?

Simmons' Precalculus Mathematics in a Nutshell: Geometry, Algebra, Trigonometry
Cohen's Precalculus with Unit Circle Trigonometry
Basic Mathematics by Lang
Trigonometry by Gelfand and Saul

Your question DOES pertain to this board, anon, because you have asked it in a polite fashion and you have not asked for help with your homework (etc)!

I think that other guy had some solid recommendations for you. Otherwise I would recommend that you read trig wikis, and set yourself problems about the unit circle.

The useful observation about right triangles, implicit in your picture, is that the 30-60-90 triangle and the right isosceles triangles are special. Not that anyone cares but I remember realizing this shortly before learning trig in HS; my "intuition" was there.

There you go OP, this is all you ever needed to know about trigonometry.
