Homework Help: Integration function*sqrt function

  1. May 9, 2010 #1
    1. The problem statement, all variables and given/known data

    I have a long integration, for finding the flux integral. One of the variables, when multiplied out turned into a function multiplied by a sqrt. I can integrate the rest of the question, just not this bit. The integrals are both between 0 and 3

    2. Relevant equations

    integral (4st^3)*sqrt(9-(s^2)-(t^2)) dsdt

    3. The attempt at a solution

    I tried partial differentiation, but got rather lost and ended with a ridiculous answer.
