## Main Question or Discussion Point

I need the partial derivatives of:

f(x,y) = ∫

are they simply:

∂f/∂x = -2xcos(x

and

∂f/∂y = 2ycos(y

or am I completely lost here?

f(x,y) = ∫

_{x}^{y}cos(t^{2}) dtare they simply:

∂f/∂x = -2xcos(x

^{2})and

∂f/∂y = 2ycos(y

^{2})or am I completely lost here?
