This page contains samples of some math software I have written in Perl and C#. The following are Perl-based interactive Web pages illustrating various math concepts:
- Modular arithmetic calculator - Do arithmetic and find square roots modulo an integer.
- Basketball statistics (Perl-based Web interfaces to a MySQL database):
- Plot the trajectory of a cannonball for a given muzzle velocity and angle of elevation.
- Graph solutions of the Lotka-Volterra equations, a model for predator-prey interactions.
- Draw graphs of ellipses with different parameters.
- Convert angles between radians and degrees.
The following are C# Windows Forms applications. You might need to use Internet Explorer to launch them.
- Poly Grapher - Draw the graph of a polynomial and its derivatives.
- Equation Solver - Draw the graphs of two linear equations and their solution.
