The Fundamental Theorem of Calculus

So I came so close to skipping class today, I was literally seconds away. I came into the classroom, and my buddies had me convinced to leave, when the professor walked in. He saw me, and my conscience won over. I couldn't just leave, even if some people do that. So, instead of sitting in Sbisa eating with Dylan, I'm sitting here, cold, hungry, and having to sit through 50 minutes of learning what I already know. Stupid conscience... This lecture seems pointless. I don't know where he's going with this... Oh. Wow. He just spent over 10 minutes explaining that the derivative of the integral of a function is that function. Next week can't get here fast enough.
