I just took a precalc test this morning on two of the 3 trig chapters in our book. I think I did okay, but is there anything else in the world as unnecessarily difficult? Mostly because I have a bad teacher, but damn...how does
tan2x = 2tanx/(1-(tanxtanx))...who the fuck realized this? Whoever it was, I hope they died a slow painful death.
