PDE Diffusion Problem Help

  1. Jan 16, 2012 #1
    I am utterly lost on this problem. This is from Applied Partial Differential Equations by Logan, 2nd edition.

    Unfortunately, I can't show any attempted work because I don't even know where to start!

    In the example, they are using some sort of method for solving and ODE, and I have no idea what.

    I really need help with understanding in words what they want me to do, and baby steps in how to do it.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
