I'm trying to solve this problem in mathemtica:
You can use Mathematica to explore solutions to the wave equation, utt = c2 uxx.
1. Use DSolve to compute the general solution and interpret the result of the wave equation.
2. Consider an infinitely long string with initial position
b = (b |x|/a for x < a
0 for x > a"
and initial velocity Psi(x)=0.
Use yor solution from 1 to construct a series of pictures showing how the wave travels down the string (you
will need to . This will depend on the relationship between 0,
