You could of separated it from the beginning first: \[\int\limits \frac{ \sec^2(x) }{ \tan^2(x) }dx  \int\limits \frac{ 1 }{ \tan^2(x) }dx \] use usubstitution: u = tan(x) du = sec^2(x) \[\int\limits \frac{ 1 }{ u^2 }du  \int\limits \frac{ 1 }{ \tan^2(x) }dx\] and you know: \[\frac{ 1 }{ \tan^2(x) }= \frac{ 1 }{ \frac{ \sin^2(x) }{ \cos^2(x) } } = \frac{ \cos^2(x) }{ \sin^2(x) }= \cot^2(x)\] proceed: \[\int\limits \cot^2(x)dx = x\cot(x)+C\] PUT EVERYTHING TOGETHER: \[\frac{ 1 }{ \tan(x) }(x\cot(x))+C\]

The int of sec^2 is tan. You dont need any other steps to compute that.

the sec^2x cancel out leaving 2/sec^2x which is 2ln(tanx) right
