I said last week that I liked that things were being brought back from other classes into the things we were working on, and now I see trig is being brought back, and that was my favorite math course. I still don't understand radians though. Putting the derivative in relation to time was genius, who ever came up with that should be acknowledged, I would have never thought of that. So far calculus has been surprisingly easy, with only a few hiccups here and there. This was one of the easier portions of the course in my opinion.
