How do you integrate [tex]\int secx^{3}tanxdx [/tex](adsbygoogle = window.adsbygoogle || []).push({});

I'm substituting [tex]u = tanx [/tex] so [tex]du = sec^2xdx [/tex]

Now the problem is when I made sec^3x in to sec^2xsecx then I had a secx left over after my substitution. What do I do with this?

PS: Sorry I'm new at latex and I dont know how to get rid of that {
