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.
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:
A student should feel free to use any resources, such as ODEToolkit from Harvey Mudd College,
Wolfram Alpha, http://www.
VODE F90 Ordinary Differential Equation Solver,
Intel Ordinary Differential Equations Solver Library,
Many software codes can be found on Math Forum:
and General resources and methods for ODEs web site:
You are free to use available user-friendly packages such as Iode
that runs under either Matlab or Octave or the Matlab packages
developed by Professor John C. Polking, who made them available for educational purposes
