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.
What do you mean by "how to get the functions"? Which functions? What do you mean by "how to get"? Are you asking how to solve the pde?
