4.6: PDEs, Separation of Variables, and The Heat Equation ...
2021-7-2 · The method of separation of variables is to try to find solutions that are sums or products of functions of one variable. For example, for the heat equation, we try to find solutions of the form. u(x, t) = X(x)T(t). That the desired solution we are looking for is of this form is too much to hope for.
