Homework Help: Improper Integral Confusion

  1. Feb 28, 2010 #1
    1. The problem statement, all variables and given/known data

    from x= -[tex]\infty[/tex] to x=2

    2. Relevant equations

    No specific ones.

    3. The attempt at a solution

    So, from there I tried to split the integral into two, integrating between 2 and -2, and -2 and -[tex]\infty[/tex], but I got very lost trying to take the limits for these, partly because I don't know what to set as the approaching variables in each case. And integrating the function actually is another issue. Could someone take a look?

    I think you need to integrate that over.

    [tex]\int \frac{1}{x^2+4} \neq lnG(x)[/tex]
