Re: The Wave Equation : Mathematica vs. Mathworld

Dear Math User Group:
Some of you pointed out that I failed to transcribe the Wave Equation 
accurately in my notebook, and I acknowledge, and apologize for my
My question is really: How can I set up the Wave Equation using
Mathematica (with the same Boundary, and Initial Conditions as shown
in the Math World webpage) so that one can get a solution similar to
Eq (39)in Mathematica?
The example given using Mathematica's Help Browser (and found by
typing "wave equation" in the search box) is simpler because it lacks
I.C. and B.C.  And it is not clear how one can introduce the I.C. and
B.C. by modifying the evaluation commands shown in that example.
Thank you for your insight!
