I have an integral problem that I'm working on, it's a polynomial which I imagine either can't be factored or needs to be completed, and then substituted using a trig identity:


If someone could give me a hint at how to start tackling this problem, I'd really appreciate it - just need a jumping off point as I feel a bit stuck.



Hint: Using partial fractions


And by the way, this is not a polynomial. It is a rational function.
