$\displaystyle

\int {(15sinx+6tanx)}dx

$

So I broke it up

$\displaystyle

15 \int {sinx} + 6 \int {tanx}

$

Then got...

$\displaystyle

{-15cosx-6ln|cosx|}

$

I know its right however I don't know if I was taught the integral of tanx, so I was wondering if there was any other way of doing it?
