I am utterly lost on this problem. This is from Applied Partial Differential Equations by Logan, 2nd edition.(adsbygoogle = window.adsbygoogle || []).push({});

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
