How can I do a symbolic resolution in SMath-Studio?
In mathcad there are: simplify, expand, substitute, etc.

When I solve an equation, I have to use "maple". Can this be done without using it?

The built in symbolic engine in SMath leaves much to be desired.
I know the maple plugin has at least some of the functionality you're looking for. Also you'll want to check out the Maxima plugin as that's very useful for solving symbolic equations as well.

Maple and Maxima plugins has symbolic simplify functions.
Unfortunately SMath don't have this features natively.

You can write your own functions to make expand(),simplify() work as if they are implemented.
Don't sure if they will work with complicated function, but they are fine with simple ones.

Alvaro thank you very much, your solution has worked very well for me. I have a question, you use commands like "Collect" and "Opt" but they don't appear in "all my functions"; The program executes the commands but it does not allow me to see their description or know what they are for, are they from a complement?

Jean thank you very much for sharing your examples, they are great. I have a question, you use commands like "Conver" "Collect" "dsolve" and "invlaplace" but they don't appear in "all my functions"; The program executes the commands but it does not allow me to see their description or know what they are for, are they from a complement? what are they for?

How did you put so many "boolean equals" without the parentheses being uncertain?
¿Cómo pusiste tantos "iguales booleanos" sin que los paréntesis sean inciertos?

Thank you

They just make the demand produce/solve.
Few more attached as you may need eventually.

Opt = Symbolic or Opt = None means that you must to right click over an expression, and choose Optimization / Symbolic or None, not a command.

About collect and other expression they aren't from SMath, but from Maple plugin, which is Maple version 6. So, you must to learn something about it. Maplesoft online help could be very extended: Maple help but you can also read some good manuals like "Aprenda Maple 8 como si estuviera en primero" from Universidad de Navarra (you can google it, it's free). Just a notice: Maple V have several differences about how handle strings and some other things, so if you can't find a good short manual about Maple 6 try only up versions.

Best regards.
Alvaro.

With some hard work you can hack the SMath syntax: From https://en.smath.com/for...-requests.aspx#post56111

The continued fractions are not futile ... Explain.
Before the modern CAS, the main frame IBM, used continued fractions.
As well as the J_Fraction... Where is my Mathcad on that ?
Since then, the Padé normalized fractions have replaced
the continued fractions, more stable numerically, faster parallel.

This is nice. I didn't know it could be done.
Formulas work even after brackets removed.
Not just a cosmetic removal.
Thanks a lot.
