The function wave2 takes in three parameters: f - The initial displacement, written as a function of r and th (I'm using th instead of \316\270 because it is easier for me to type, and I don't like using palettes). g - The initial velocity, written as a functino of r and th. k - The number of terms you want to the solution that you want to use. Note that since this is a double sum, you will actually use about k^2 terms. 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. JSFH
