(15 pts) Bessel functions and the vibration of a circular drum In polar coordinates, the Laplacian is just like the Laplacian for the cylinder, but with the removed part เอ The structure of the Laplacian is what we call separable because the r and 0 terms are separate this allows us to solve certain physics problems on the disc by searching for solutions of the form f(r,0)-ar)b() The vibration of a circular drum head is described by 02t where u...

This rotational invariance suggests that the two-dimensional Laplacian should take a particularly simple form in the polar coordinates (x,y) (7.8) given by x-r cos θ and y-r sin θ. By the chain rule, it is indeed rewritten as Show *
