3/11 - #42

Today was the first day back from spring break, and it was very fun! I got to see all my friends again, and we immediately all started arguing over who slept the most over break (it was me). We had precalc first, and it was so much fun working on trig identities (it was not fun, I'm still working on it even though we had 90 minutes to work on it in class). The practice problems were easy, but the homework was horrible. Eventually, I'll understand them, but maybe not today. I mean, how did they figure out sec^2θ-tan^2θ=1..?!
