Calc III help requested

  1. Dec 4, 2004 #1
    From what I can remember, this wasn't covered in my class, however it was a bonus question on a test, and I was wondering if someone could take the time to enlighten me on this one.

    Find [tex]\frac{\delta f }{ \delta x} [/tex] and [tex]\frac{\delta f }{ \delta y} [/tex] when

    [tex]f(x,y) = \int _x ^{x^3y} \sin (t^2) dt[/tex]

    This may help:

    [tex]\frac {d}{dx} \int^x f(x') dx' = f(x)[/tex]
