Hello everybody.(adsbygoogle = window.adsbygoogle || []).push({});

I don't know how to find solution and to draw it for this wave problem:

Uxx+Utt=0

U(x,0)=0

Ut(x,0)=1 a )for 0<=x<=1 and

Ut(x,0)=0 otherwise.

I have to draw the grafic for t=0, 1, 2 for x element from -5 to 5.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
