I would like to ask some questions regarding my coursework, which is about 2nd ODE and multivariable calculus.

Since we have the one-dimensional wave equation and values for the string stretched between x=0 and L=2: 0≤x≤L, t≥0

The string is fixed at both ends so we have :

u(_,t)=u(_,t) = 0 , t≥0

now we assume string is raised a distance μ at x=b and released from rest at t=0, Zero velocity implies: ∂u/∂t (_,_)=0 . 0≤x≤L

thanks beforehand!
