Hi all. I am trying to get Mathematica to solve a partial diffy q that looks like this:
V is a function of x and t V=V(x,t).
d^2V/dx^2 - V - dV/dt = delta(x)delta(t)
where delta is the dirac delta function (DiracDelta[x])
this is what i input:
DSolve[ D[V[x, t], {x, 2}] == D[V[x, t], t] +
V[x, t]+DiracDelta[x] DiracDelta[t], V[x, t], {x, t}]
and I get no answer. does anyone have any suggestions?
