I tried to simplify the trig functions into or but nothing helped

Try a hyperbolic substitution x=3th(theta), it will work.

works reasonably well.
There are a number of ways to do it, but the way ReneG attempted it works fine as well, it was just the remaining trig that had to be worked out.
My calculus 1 class did not involve integrating csc(x), that is why I offered the simpler hyperbolic substitution.
