Find the solutions to in two and three dimensions subject to the following boundary conditions
(a) for and for
(b) for and for
Note that the boundary conditions do not depend on or (in 3D)
I'm having trouble understanding exactly what the initial conditions are saying here.
If I had to solve this PDE with conditions (another question I have):
I would do it as follows:
Assume :
So
and
Solving these,
and
and so
.........(Eqn 1)
Then applying all conditions and skipping a few steps the solution is
But I'm getting confused with the initial conditions here, and how to go from Eqn (1) onwards with the intitial conditions onwards i.e.
(a) for and for
(b) for and for
For the 3d case, I have
Assume
Then
Dividing through
Which results in 3 ODE's
which have solutions
So, due to superposition,
which is all I have...I don't understand the form of the initial conditions.
