RE: RPN mode
How about CAS functions and commands on the Home view in RPN mode? It looks like everything is possible in RPN mode, all CAS functions and commands works. There are some tricks needed in some cases. Unfortunately, RPN is poorly described in the user manual.
Found how to use in RPN mode Simplify, Collect, Expand, Factor... In usual way these commands numerically evaluate the expression with variable value in RPN mode, for example,
'2*X^2-4*X+2' Enter CAS.factor(1) Enter returns 2 if X value is 0.
There must be small letter x, but with small x '2*x^2-4*x+2' Enter causes Syntax Error. Found that expression in double quotes instead of single quotes fits very well.
"2*x^2-4*x+2" Enter CAS.factor(1) Enter returns 2*(x-1)^2
With capital letter X works notation where every X is in single quotes:
'2*'X'^2-4*'X'+2' Enter CAS.factor(1) Enter returns 2*(x-1)^2
Long live RPN Smile
