Using the FTOC and attemting to find the derivative of [tex] g(x) \int^x_0 tan^2 2tdt [/tex] I made [tex] u=tan^2 [/tex]. I know it will wind up being F(x)-F(0) but I'm at a loss with what to do with the 2t. Am I on the right track or have I chosen the wrong u?(adsbygoogle = window.adsbygoogle || []).push({});

If you could, please guide me and don't spell out the answer.
