Proper way(s) to substitute X for x in a CAS expression

[cyrille de brébisson]

Hello,

Quote:Unfortunately, when storing this in Function.F1 using
X^2-5 Sto> F1 or F1:=X^2-5
The expression is evaluated (using real X value) which results in a real value in F1, not the expression.

Yes, in the same way that you would expect A:=1+2 to result in A=3 and not 1+2...

try using QUOTE (or '') as in:
F1:='X²-5', it will work...
QUOTE(input) (or 'input') stands for "do not evaluate what is inside" and is used just for that type of cases.

Merry xmass!
