Creates Iterated Function System (IFS) Fractals with touch zoom in/out. There are 16 built-in definitions, plus users can store custom definitions in L0 to generate their own images.
Uses a converging iteration technique ported from a QBASIC program by Gérard P. Michon to calculate the perimeter of an ellipse. Also includes a version using integration that is slightly more accurate.
A collection of small programs that are useful for Calculus: Graph Integrals, Riemann Summs, Trapezoid Rule, Simpson's Rule, Simpson's 3/8 Rule, Monte Carlo Integration, Newton's Method, Method of Bisectors, calculate arclengths, error function.
