Question: Integral of partial derivative problem

When I integrate the partial derivative of v(x,y) with respect to y from y = 0 to y = Y using


int(diff(v(x,y),y), y=0..Y)


Maple simple echos the integral in typeset format. I expected to get


v(x,Y) - v(x,0)


What am I missing here? This integral comes from integrating the 2D continuity equation in boundary layer. Any help would be greatly appreciated.
