Here's the question:(adsbygoogle = window.adsbygoogle || []).push({});

We want to evaluate the improper integral

http://ada.math.uga.edu/webwork2_files/tmp/equations/6c/4073055a5b909be16e2abc5bd3dfc61.png [Broken]

Do it by rewriting the numerator of the integrand as http://ada.math.uga.edu/webwork2_files/tmp/equations/cf/4f71fa0eec36e407d3cf7df46ef3621.png [Broken] for appropriate f, g and h and then reversing the order of integration in the resulting double integral.

I don't know what this means?

Would the integrand in the numerator be x from tan ^-1(x) to

tan^-1(pi*x)?

Thanks a lot.
