I've spent a lot of time on it and I could only go so far. I think it's option 4, but I can't see how. Maybe I need to brush up on logarithms. Sorry I wasn't able to go till the end, but I spent 40 minutes on this, and I thought I might as well tell you what I've got, or it would be a wasted 40 minutes.

Hope this helps at least a little





Use trig identity:









I've just memorized the integrals of cosecant and secant, but they aren't too impossible to do.

Thanks so much, it was in fact 4. The division step gave it away.
