Computing triple integral

  1. Mar 8, 2009 #1
    1. The problem statement, all variables and given/known data

    Can anyone tell me if I did any mis-computation on evaluating the triple integral above?

    2. Relevant equations



    3. The attempt at a solution

    The image is too small and grainy for me to read clearly....could you upload a larger version of it?

    That's much better, and also correct:approve:

    (Although it's only a double integral, not a triple integral as the thread title suggests)

    so all my computations there are all correct?

    Edit: no, you have an extra factor of 2....

    yes, you brought the 2 inside the integral in order to compute the antiderivative of 2re^(-r^2)dr....but on the next line of your calculation, it was back outside the integral
