The Mathematical Parameters dialog box allows the user to edit some more advanced features of the simulation.

Step Size- The step size specifies the interval over which the Runge Kutta method estimates the slope of the velocity and position variables. Using a smaller step size will yield a more accurate representation of the actual solution to the coupled differential equations. Increasing step size will, however, slow the rate of execution of the program.
NOTE: Using a negative value for the step size will allow the simulation to model the system backwards in time!

Simulation Speed- The simulation speed specifies the amount of time which the programs timer waits between consecutive calculations of the position and velocity. This number represents the interval in microseconds, so decreasing this number will increase the execution speed of the program.
