Here's what I got: Let y = y=(x,t) and a^2=tau/mu. Then y_tt = a^2(y_xx) and y(L/2,0)=h, y_t(x,0)=0, y(0,t)=0, y(L,t)=0.

Please confirm if this is correct or not.

@tmauldin: haha thanks, i appreciate it. that's alright, my homework isn't due until 11/21 anyway, I can wait or repost this tomorrow or sometime again so that someone online who's capable could see it.
