String attatched at x=0 and x=L, string is at rest, initially y is
Initial conditions: dy/dt=0 with t=0
y(x,0)= 2H*x/L 0<=x<=1/2L
Just struggling to see where the boundary condition y(x,0) is generated from?
I guess it has something to do with the conditions before,
any help will be appreciated, many thanks.
