I know that the equation of a standing wave in a string is y=2Asin(kx)cos( ωt)$y=2A\sin(kx)\cos(\omega t)$. I also know that the displacement of a node is zero, hence it has zero kinetic energy. How do iI find the total energy per unit length at t=0$t=0$ and x=0$x=0$?

What is the energy at different points of standing wave?
