The trig functions.
I've seen and understand the regular pi using graphs, the triangle side angle relationships, etc.
What I wan't to know is a reason why those connections exist with the functions(angles to sides), what the functions and inverse functions are doing to transform values from one thing to another, and a deeper understanding of the why and how they came about.
I know how to do powers in functions by multiplication, multiplication by using addition, division by doing substractions, but I'm not sure how to do square, cubic, etc roots with simpler math in functions.
Also I've read and seen info on the dot product, but would like additional intuitive info.
