I found this unit quite challenging...Basically, this unit we learned about trig identities. The main thing we did in this unit was prove how two identities or expressions (or something) are equal. We learned that while proving that they were similar, we were not allowed to allow numbers, variables, etc. to cross over to the other side of the equal sign, or as Mr. K. says, the Great Wall of China. We were exposed to some other material such as how some identities are derived from cos^2 + sin^2 = 1. I understood how most of them worked, but i also had trouble understanding some of them. I think that was pretty much what we learned, and if it's not, then i guess you can tell that i still need a bit of help in this unit. Good Luck at the Test Everyone!
