Best ResponseYou've already chosen the best response.3this is just a test idk if it will work \[\int sec^2 x* sec^2 x*\sqrt{tanx} dx\]

Best ResponseYou've already chosen the best response.3\[cos^2 x + sin^2 x= 1\] \[1+tan^2 x=sec^2 x\]

Best ResponseYou've already chosen the best response.3you could use trig subs

Best ResponseYou've already chosen the best response.3trig sub will work with any trig integral... it's just a pain for something that can be done easier anyways \[\int sec^2 x *(tan^{3/2} x+ \sqrt{tan^{1/2}x})\]

Best ResponseYou've already chosen the best response.3\[\int sec^2 x*tan^{3/2}x dx + \int sec^2 x*tan^{1/2}xdx\]

Best ResponseYou've already chosen the best response.3let \[u=tanx\] \[du=sec^2 x\] \[\int u^{3/2}du+\int u^{1/2}du\]
