Mathematica Question

  1. Mar 8, 2010 #1
    Hey all,

    I'm trying to solve a PDE in mathematica of this form:

    d^2 f / dx^2 = df/dt + f

    where f is a function of x and t.

    So I input this:

    DSolve[D[V[x, t], {x, 2}] == V[x, t] + D[V[x, t], {t, 1}],
    V[x, t], {x, t}]

    does anyone know why no answer shows up? thanks.

    It doesn't have a general analytical solution. You will have to do it numerically or use some other problem decomposition.
