Hello everyone! so I want to know how to plot/(get the answer also) to this Second order partial differential equation on wolfram alpha, or actually any program that can do it online. so it goes like this:
Solve: Uxx + Uyy = 0 for 0 < x < L and 0 < y < L
At x = 0, U = 0
At y = 0, U = 0
At x = L, U = 0
At y = L, U = f(x)
being Uxx = d^2u/dx^2 and Uyy=d^2u/dy^2
MANYYYY MANY thanks
