Guys guys guys, I seriously just had to wiki Trig to remember that sin A = opposite/hypotenuse, cos A = adjacent/hypotenuse, tan A = sin A/cos A = opposite/adjacent.

I seriously forgot SOHCAHTOA. I'm losing my mind :(

Yeah, my calc textbook was just okay. It was a monster of a textbook though, but the Bio ones are worse - I weighed my Bio textbook last week, and it was SIX POUNDS. It weighs as much as a LAPTOP plus CABLES. --'' My calc textbook though had all the trig identities. . . on different pages. . . throughout the book. . . so to find certain ones you had to flip through it like crazy and half the time you wouldn't even find it again. --''
