JSFH Solutions to the symmetric wave equation on a disk. The function wave1 takes in three parameters: f - The initial displacement, written as a function of r. g - The initial velocity, written as a functino of r. m - The number of terms you want to the solution that you want to use. To keep from having too many inputs, the program assumes that c = 1 and a = 1.

Simply play with the program. Change f and g in the input, possibly change m, possibly change the range of t in the animate command (you can also change the number of frames if you want). Basically, make something cool, and then bask in the glory of your vibrating membrane.
