Not sure how to do this. How do I integrate tan^2x?

There is no knowledge that is not power.
Derive the general reduction formula and you can use it for any power of tangent:
[tex]\L\\\int{tan^{n}(x)}dx\\=\int{tan^{n-2}(x)tan^{2}(x)}dx\\=\int{tan^{n-2}(x)(sec^{2}(x)-1)}dx\\=\int{tan^{n-2}(x)sec^{2}(x)}dx-\int{tan^{n-2}(x)}dx\\=\frac{tan^{n-2}}{n-1}-\int{tan^{n-2}(x)}dx[/tex]
Hello, dagr8est!
[tex]\L\int\tan^2x\,dx\:=\:\int\left(\sec^2x\,-\,1)\,dx[/tex]
Can you finish it now?
I'm the other of the two guys who "do" homework.
