    This might get you started, but if you want to try to do it mostly by yourself, just read a line at a time until you get it:

    \int\csc x\sec x\,dx

    =\int\frac{dx}{\sin x\cos x}

    =\int\frac{\sin x\,dx}{\sin^2 x\cos x}

    =\int\left(\frac{\sin x}{\cos x}\right)\left(\frac1{\sin^2x}\right)dx

    =\int\tan x\csc^2x\,dx

    Can you manage from here?
