I learned that shit all throughout the year, and we are starting on some basic trig now, sine cosine and tangent and whatnot. Kinda confusing right now, because we just started and I've never done this before.
EDIT: Oh yeah, calculus. I plan on taking it junior or senior year. Probably going to take Pre-Cal or Trig next year, which would be my junior year for math, since I get to do math from a grade above me.
