Homework Help: Integration strategy?

  1. Sep 21, 2008 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    This is the result of a partial fraction integration. I don't think a direct u-substitution will work or an integration by parts.

    3. The attempt at a solution

    I don't know which I should use! We learned so many and none seem to work nicely in this case. Should I try to do a trigonometric substitution? That is my best guess, but since there is no radical I have no idea how to implement it!

    Any sort of hint would be great. I'm just not "seeing it" ;)

    Complete the square of the denominator then break it up using (a+b)(a-b) = a^2 - b^2. From here you can do it by partial fractions, though it appears tedious.
