Mathematica Example Notebooks

A wide range of Mathematica example notebooks used in the graduate Math Methods course are available. Take a look!

If the notebook doesn't open automatically in Mathematica when you click on the link, "right click" to save it first (to the Desktop or a session folder) and start it from within Mathematica.

Last RevisedNotebookComments
23-Sep-2011 Calculate area A simple Mathematica notebook defining a function to calculate the area of a circle, including forcing numerical output and multiple definitions of a function with different numbers of arguments. Also, making it into a program.
23-Sep-2011 Defining n! Mathematica notebook with many ways to define n!.
23-Sep-2011 Rolling dice Mathematica notebook that simulates the rolling of dice, where the outcome is a random integer from 1 to 6. Histograms are generated for different numbers of "trials" (i.e., throws of the dice), providing visualization of how the fluctuations scale with the number of trials.
25-Sep-2011 3D Square Well Mathematica notebook to find the eigenvalues of a spherical three-dimensional square well by matching solutions.
12-Feb-2009 Nonlinear Differential Equations Mathematica notebook analyzing the Duffing equation.
12-Feb-2009 Nonlinear Differential Equations: Pendulum Mathematica notebook analyzing the physical pendulum.
