## Homework Equations

All shown in the above link, AFAIK

## The Attempt at a Solution

Not worried about part a.

For part b, when they say "assume the string is initially at rest" I took that to mean:

[tex]\frac{\delta\Psi(x,0)}{\delta t}=0[/tex]

But I don't know if that is right. It would be used as some sort of initial conditions for solving some diff eq. But I don't understand what that diff eq would be, or how to set it up. I would imagine I solve this diff eq using sep of vars?
