What methods or tricks are there to approach antiderivatives, beyond what's learned in Calculus II? I'm just talking about ordinary, analytic stuff like [tex] \int \sqrt{ \tan x } dx [/tex] not requiring 'special' functions. I mean, the integral tables were around for a while, right, so how did they solve all those things?(adsbygoogle = window.adsbygoogle || []).push({});

edit: by 'beyond Calc. II' I mean other than things like

-clever substitutions

-method of partial fractions

-integration by parts

-series expansions

etc.
