Dear group,
Could you tell me who to get the general analytical solution of the following function
1. Uxy - Uy = 0
2. U + 2 Ux + 2 Uy +4 Uxy = 0
U is function of x and y.
Something strange is: although I can calculate the general solution by hand for the first equation easily, I can't use mathematica to get the solution.
I have tried two ways:
~ the DSolve and
~ the following way
<<Calculus`DSolveIntegrals`
CompleteIntegral[Derivative[1, 1][u][x, y] - Derivative[0, 1][u][x, y] == 0,
u[x, y], {x, y}]
Thanks a lot!
Li
