How would I go about solving this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int cos^2x tan^3xdx[/tex]..all i did so far ..

[tex]\int cos^2x tanx(tan^2x)[/tex]

[tex][[ \frac{1}{cosx}^2 -1] = tan^2x[/tex]

so...

[tex] \int cos^2x[[ \frac{1}{cosx}]^2-1]tanx[/tex]

is this right so far...now what?
