I initially tried rewriting tan^2(x) as tan(x)tan(x) and then doing integration by parts. At some point, I needed the antiderivative of tan(x) and decided to see what I could get by rewriting tan(x) as sin(x)/cos(x).

As you can imagine, my notebook looks like the math equivalent of attempting to extinguish a flame with -gasoline- liquid oxygen.
