Integrate 1/(1-secx)dx by multiplying the integrand by a form of 1.

2. Relevant equations

any sort of trig identity?

3. The attempt at a solution

I've tried multiplying by forms of 1 such as secx+tanx, secx-tanx, and others, but when i do, i just end up with a messy looking integrand.

any pointers with this and any other problems like it?
