6. (20 pts; 15 pts for solution, 5 pts for plots) Find the vibrations of a circular drumhead of radius 1 m and area density 2 kg/m², given a tension of 8 N/m, an initial velocity of 0.0 and an initial displacement of f(r) = 2r2 - 2 (in m). Recall that c = T/p. Do use results derived in class/homework, and do show the details of your work. Plot your result at several time values, or produce an animation.
