Write the BVP for the small vertical vibrations of a homogeneous string. Assume that the wave's speed is c.(adsbygoogle = window.adsbygoogle || []).push({});

Problem: take L = 2[Pi] , c= 2,

SUppose that the right end is fixed while the left end is allowed to move vertically. At the left end, the tangent line at any time t is horizontal. Suppose that the string is set into motion from rest with an initial position given by the function f(x) = sin3x

Write the BVP

Solution:

u(x,0) = sin3x

[tex] u_{t}(x,0) = 0[/tex]

u(2[pi], t) = 0

u(0,t) = f(x) since the left end is allowed to move vertically ( is this right? )
