Computer Resources

There are plenty of avalable software resources to help a student to plot direction fields, find solutions of differential equations and to print their visualizations. The main tutorial for this course is tutorial.

There is a friendly graphical program, Winplot, written by Richard Parris,

a teacher at Phillips Exeter Academy in Exeter, New Hampshire. Mr. Parris

generously allows free copying and distribution of the software and

provides frequent updates. The latest version can be downloaded from the website:

http://math.exeter.

A student should feel free to use any resources, such as ODEToolkit from Harvey Mudd College,

http://odetoolkit.hmc.

Wolfram Alpha, http://www.

VODE F90 Ordinary Differential Equation Solver,

http://www.radford.

Intel Ordinary Differential Equations Solver Library,

http://software.intel.

Many software codes can be found on Math Forum:

http://mathforum.org/

and General resources and methods for ODEs web site:

http://www.scicomp.

You are free to use available user-friendly packages such as Iode

http://www.math.uiuc.

that runs under either Matlab or Octave or the Matlab packages

**dfield8.m**

or

**pplane8.m**

developed by Professor John C. Polking, who made them available for educational purposes

http://math.rice.

**R** is a programming language and software environment for statistical computing and graphics. R was created by Ross Ihaka and Robert Gentleman^{]} at the University of Auckland, New Zealand, and is currently developed by the *R Development Core Team*, of which Chambers is a member. R is named partly after the first names of the first two R authors and partly as a play on the name of S.

There are two free computer algebra systems:

Sage: http:/sagemath.org (available also in clouds)

wxMaxima: http://sourceforge.net/projects/wxmaxima/ (the first computer algebra system in the world)
