I finished up Algebra I, Geometry and Trigonometry at the Kahn Academy website, and I have moved into Calculus. Some of it gets complicated, and I have troubles with making dumb mistakes, as always, but I am moving through it at a slow but steady rate. I can differentiate all sorts of things, but I have yet to see any purpose in it. Is this all just mental gymnastics? How can this be applied in life? I am only 38 percent of the way through, so maybe it will become clear as I move along.
As of yet, I am not enjoying it as much as the Geometry and Trig, but maybe I will as things all pull together.
