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.
