Question

If a string of length l is initially at rest in equilibrium position
and each of its points is given the velocity dy/dt= b sin^3πx/l find
the displacement

Accepted Answer

the displacement y(x,t) is given by the equation frac{d^2y}{dt^2}=a^2 frac{d^2y}{dx^2} The boundary conditions are (1) y(0,t)=0 for t>0 (2) y(l,t)>0 for t>0 (3) y(x,0)=0 for 0
