Ok, one of my homework problems for my calculus class is the following:

integral (0.5 to 1) [(x^2tan^-1(x) + 3x + 1)/ x^4 + x^2] dx

here is a link to a picture of in case it doesn't make sense the way i typed it.

I really don't know how exactly to solve it. I have never done any where the inverse tangent is on the numerator. Can I get some help?
