Using the ilapalce command in CAS, I have obtained an expression in the variable t.
Now I want to plot this function using the Function App, so I run the App and import the CAS expression pressing the Menu key and selecting Get from CAS. Then, before pressing Ok I have to manually substitute X for t all over the expression, because X is the only variable name accepted by the Function App.
What I'd like to knows is if there is an easer way to substitute X for t in CAS before switching to the Function App, or inside the Function App.
The command subst(expression, t=X) does not work because X is a real variable with default value 0.
