    The anti-derivative does not exist as an elementary function. Why do you need it? Please post the whole question.

    this integral has no elementary, closed-form antiderivative.

    The only thing worse than this thread is this thread.

    Never would have guessed this from OP. (Still a bit ambiguous, but assuming the following.)

    f(x,y)=\int_y^x\ e^{(t^2)}\,dt

    Use the Fundamental Theorem of Calculus to find \frac{\partial f(x,y)}{\partial x}\,, \ \ \frac{\partial f(x,y)}{\partial y}\,.

    Indeed. Yet again we see what happens when the OP only posts what s/he thinks is necessary rather than posting the whole question.
