    You need to make a substitution, read this

    I don't understand the question. That is "one dimensional" integral, in a single variable. How do you intend to change it to a three dimensional problem?

    There is a method for integrating \int_{-\infty}^\infty e^{-x^2}dx by: Squaring then writing it is the product of two integrals in x and y, then converting to polar coordinates. But that method won't work here because it depends upon the fact that [tex]e^{-x^2}[/math ] goes to 0 at both \infty and -\infty.
