Not really a homework problem, but this is just a problem that's been bugging me for a while: how would you find ∫sec2x dx without "cheating" and using the simple fact that d/dx tanx = sec2x? I know it's possible using integration by parts, but I'm looking for a way using calc I level techniques, like u-substitution. So far no success. Any ideas?
