What is the integral of ln(sec(x))...... if you can post the method, it would be cool too.

Here's the integral:

integral ln(sec(x))

Haven't a clue how it's obtained though!

(Because it's an indefinite integral you should add a constant, not shown above.)

I just cant figure out how to derive the integral. I will hopefully figure it out soon.
