Linprog provides a graphical inteface for solving a 2 dimensional linear
programing problem

SetShd is for student who want to practise with set theory. It allows
the user to practice shading a Venn diagram. It also has a test module
to test their understanding of the use of Venn diagram to represent
set theory.

Transfxz helps students to visualize how 2D linear tranformations are
carried out. It animates the tranformation process. There is also 2 
test modules.

Each of the program has its own help system.

These programs were first developed in 1992. Linear programming, Set
Theory and Transformation were then included in the Cambridge GCE O level
exams. I believe these topics are still in the syllabus.

These programs has help many of my students to understand these topics better.
I hope they will be useful to you too.
