Hello friends  can anyone please direct me to a webaddress to assist in solving a particular partial differentian equation. It may be familiar to you: I think its called the second order LaPlace equation (please excuse the notation):
d2u/du2 + d2u/dy2 = 0. I have notes to help me solve it if all four sides of the rectangle (Dirichlet?) are functions of u.... but cannot find how to solve 'mixed' form.... I hope this made sense... Thanks in advance
