dz =(−sinx + 2xy^2)dx +(2x^2 y)dy

Integrate the differential to find the function z.

Would I say that z was equal to two separate differentials and integrate the first part of the function with respect to x and the second part with respect to y?

z = cosx + x^2 y^2 + x^2 y^2 + C

z = cosx + 2(x^2 y^2) + C

Is this right or have I gone wrong?
