So I get this ?
z = a - x = a*sinw(L-y) / sinwL
dz/dy = -w*acosw(L-y) / sinwL
d^2z/dy^2 = -w^2*asinw(L-y) / sinwL
= -w^2 * 2
If this is what you were reffering to, what happens now ?
Where did the *2 come from? You mean *z. So
d^2z/dy^2 + w^2*z = 0
Compare this to your DE and identify omega. Put your expression for z into the defining equation for z and solve it for x.
