I haven't done calculus yet, but do you have a graphing calculator, like a TI-83 or something? Just stick it in there. That's what a calculator is for. Okay, I guess this is the easy way and defeats the whole purpose, but are you going to be allowed to use calculators on your test?

I hadn't even known what a "principal value" was until I just read up on it -- and I still don't fully understand it. Perhaps that's because I haven't had calculus class yet (will have it in another two years) and don't know even a bit of it.
It's been so long since I have done these kinds of problems, that I don't remember how. However, I am pretty sure that this is trigonometry and not calculus. I don't see any integrals or derivatives here.
