You can give much more complicated equations and ask it to integrate, differentiate, find roots, and many other mathematical operations. This program has a pretty large learning curve, but once you get over the top of the curve it is a very powerful tool for doing all kinds of modelling. As such, it should be quite useful in an advanced undergraduate course or in graduate courses with an emphasis on modelling biology. For more introductory level courses, the program could probably be used by an instructor to make a model which students could then play with. However, if one of the other programs described in this FAQ includes the desired model then you should probably use the specialized program.
Maple is a symbolic equation solver.
See the description of Mathematica above. Maple has the advantage over Mathematica of being faster, and having better solvers. While the program is not made specifically for education, many people use it in physiology laboratories to make data collection easy for the students. Essentially LabVIEW is a graphical programming environment that uses the construction of 'virtual instruments' as a metaphor. Traditional programming structures such as loops and cases are available.
