Question about CAS and Graphing

[CR Haeger]

Back to the OP...

Normally, if I work in CAS and end up creating function(s) that I want to plot in Function APP, then I:

1. Save the function using say f(x):=x^2 etc... // creates a CAS program f()

2. Save f(x) into Function.F1 using Function.F1:=f //Note: can use F1:=f if you are already in Function App

3. Symb view in Function App should have F1(X): function with capital Xs.

If the functions being worked on in CAS are pretty long, I like to assign them to f(x), g(x) etc. early on as it is easier to type (or use Vars/CAS/Program to select).

This works in reverse as well. Say I have been plotting functions F1, F2 etc. and want to send to CAS. In CAS I can use f(x):=F1(x), which stores F1 into f using lower case x. I can also use F1(x) directly in CAS.

Finally, to make this even quicker and reduce keying errors, I setup a few USERKEYs to prefill the CAS command line. See attachment for an example program.
