I am trying to get DiffTutor to work in Maple17, using Worksheet mode, and it doesn't do anything. Here is the code and the output. I cut-and-pasted it and the output looks weird, but you can see that Maple didn't do anything:
[Calculus1, LinearAlgebra, MultivariateCalculus,
NumericalAnalysis, Precalculus, SetColors, SetDefault,
/ / 2\ \
DiffTutor\exp\x /, x/
/ / 2\\
I will also upload the worksheet. I think that nicer-looking code will be attached to this question as a result. The worksheet may appear twice.
