[x] example that illustrates embedding animation in pdf, so that we'll generate graphs that are useful. [ ] Write code (explicit.pyx) to automate computation of each of the following. Each animation will be generated and stored as a single pdf file, with 1 page per frame. * Animation that illustrates behavior of the mean of raw data, for various curves. * Animations that illustrate computing sums over zeros for elliptic curves having various interesting symmetric power L-function properties. * Race four types of primes... for two elliptic curves. [ ] Run code for interesting curves, using powerful computers.
