I guess the following identity isn't right. Can anyone tell me what the LHS is really equal to? \frac{\partial}{\partial x}\int_{-\infty}^\infty\int_0^x f(s,t) dsdt = \int_{-\infty}^\infty f(x,t)dt

Hi guys, how would I solve this pde numerically in matlab? d^2G/dxdy+A*dG/dx*dG/dy=0 where G and A are both functions of x and y.

I am afraid not. In fact, I know G(x,y)=-ln([1+(a-1){X(x)+Y(y)}]^[1/(a-1)]) is the solution. I am just trying to figure out how to slove this pde. Thanks

d^2G/dxdy+(a-1)*dG/dx*dG/dy=0 where G is a function of x and y. Moreover, what if a is not a constant, but instead a function of x and y?
