I was given this problem and the persom whom I recieved it from told me they couldn't see how it would he solved or even if it had an answer. I think I might have come to a conclusion even thought it might be wrong, what do you guys think(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int tan^2x sec^3x dx[/tex]

this is what i've been able to conclude, might be wrong but I gave it a shot

[tex]\int tan^2x sec^3x = \int (sin^2x/cos^2x)(1/cos^3x) dx[/tex]

[tex]\int (sin^2x)(cos x)/(cos^3x) dx = \int sin^2x/cos^2x = \int tan^2x[/tex]

[tex]= sec^2x + c[/tex]

Im guessing thats probably wrong, but what do you guys think?
