**1D wave equation problem**
Hello-
I'm having trouble understanding a problem:
Consider a sealed 1D pipe of length L. At t=0, v=0 everywhere and the pressure is given by: P=P_0 +δP
and δP = (p-bar)x/L
P_0 and (p-bar) are both constants.
and I'm supposed to find density (ϱ) as a function of x and t.
I don't understand why I'm given the pressure, and how to find δϱ.
