What are you looking to do besides what is shown? You [and the students] can
graph all the 2D functions using either Graphmatica [essentially shareware, but
apparently free for those who truly do not have the means] available from the
math archives, or absolutely free "Graph" from www.padowan.dk .
OpenOffice suite is free, and so suitable for insertion of graphs and text for
reports, and has its own PDF export when done, or there are alternative free PDF
programs available, such as Primo PDF.
With Graphmatica, you can graph several related functions at once. E.G. try
a*asin(x) then change values of variable parameters for further studies.
