HAD A CALC TEST TONIGHT: It is quite satisfying to be given a problem--say, that some integral equals some number--and be asked to prove that equation is true, and plug away at it for a while, and come up with what really felt like the right answer. I mean--the steps I took produced the answer that was required. Hopefully I did not cheat with my steps. It's--mentally invigorating. Maybe I'll do calc problems in my spare time the way my mom does crossword puzzles.
