Homework Help: Am I even supposed to do the integral?

  1. Oct 18, 2009 #1
    1. The problem statement, all variables and given/known data
    I am to find the partial derivatives fxx, fxy, and fyy of

    f(x,y)= eq.latex?\int_{y^2}^{\sqrt{x}}cos(t^2)dt.gif

    The integral from y squared to the square root of x of cos(t squared) dt

    Accidentally posted, was editing to get the TEX to work
    2. Relevant equations

    3. The attempt at a solution

    All rules of integration I know fail, and attempting to use an integral calculator leads me to a term "Fresnel", which has never before been explained in my class. This leads me to assume I'm not supposed to take the integral; how, then, do I account for sqrt(x) and y^2?
