Derivative and Integral notation

[MostlyHarmless]

Why is it that when you are doing a partial derivative it is expressed something like this. ∂f/∂x=2xy, where f(x,y)=x²y but when doing double or triple integrals you see this ∫∫f(x,y)dxdy.

Why is partial notation not used in both?

There is no real connection between double integrals and partial derivatives.
