I'm so glad this exists going into my next term involving a lot of maths that I just don't fundamentally understand; sure I can remember a set of rules after boring revision of sequences of instructions but I hate that.

I asked what a "dot product" _meant_ once and was just told how it could be used to determine these other values. I later learnt what it actually was by reading some renderer library code.

I had a similar "aha" moment when I read how you described sine/cosine/etc as percentage values in relation to positions around the circle. I hate how I was taught maths since secondary school (when I was so confused at trig/pythag lessons but learnt the concepts very quickly when I was coding around with positions and angles in a game engine mod to get a position x units in front of a character instead of doing homework)

I really think this site will help me in the coming year, thank you!
