This is the front page of the SandBox?. You can try anything you like here but keep in mind that other people are also using these pages to learn and experiment with FriCAS? and Reduce. Please be courteous to others if you correct mistakes and try to explain what you are doing.

No Email Notices

Normally, if you edit any page on MathAction? and click Save or if you add a comment to a page, a notice of the change is sent out to all subscribers on the axiom-developer email list, see the [Axiom Community]?. Separate notices are also sent to those users who subscribe directly to MathAction?.

Use Preview

If you click Preview instead of Save, you will get a chance to see the result of your calculations and LaTeX? commands but no email notice is sent out and the result is not saved until you decide to click Save or not.

Use the SandBox

On this page or on any other page with a name beginning with SandBox? such as SandBoxJohn2?, SandBoxSimple?, SandBoxEtc?, clicking Save only sends email notices to users who subscribe directly to that specific SandBox? page. Saving and adding comments does not create an email to the email list. You can safely use these pages for testing without disturbing anyone who might not care to know about your experiments.

SandBox Pages

You can also create new SandBox? pages as needed just by editing this page and adding a link to the list of new page below. The link must include at least two uppercase letters and no spaces or alternatively it can be any phrase written inside [ ] brackets as long as it begins with SandBox?. When you Save this page, the link to the new page will appear with a blue question mark ? beside it. Clicking on the blue question mark ? will ask you if you wish to create a new page.

Examples

Here is a simple Axiom command:

    \begin{axiom}
    integrate(1/(a+z^3), z=0..1,"noPole")
    \end{axiom}

fricas

(1) -> integrate(1/(a+z^3), z=0..1,"noPole")

$\label{eq1}\frac{-{{\sqrt{3}}\ {\log \left({{3 \ {{a}^{2}}\ {{\root{3}\of{{a}^{2}}}^{2}}}+{{\left(-{2 \ {{a}^{3}}}+{{a}^{2}}\right)}\ {\root{3}\of{{a}^{2}}}}+{{a}^{4}}-{2 \ {{a}^{3}}}}\right)}}+{2 \ {\sqrt{3}}\ {\log \left({{{\root{3}\of{{a}^{2}}}^{2}}+{2 \ a \ {\root{3}\of{{a}^{2}}}}+{{a}^{2}}}\right)}}+{{12}\ {\arctan \left({\frac{{2 \ {\sqrt{3}}\ {\root{3}\of{{a}^{2}}}}-{a \ {\sqrt{3}}}}{3 \ a}}\right)}}+{2 \ \pi}}{{12}\ {\sqrt{3}}\ {\root{3}\of{{a}^{2}}}}$

(1)

Type: Union(f1: OrderedCompletion?(Expression(Integer)),...)

And here is a REDUCE command:

  \begin{reduce}
  load_package sfgamma;
  load_package defint;
  int(1/(a+z^3), z,0,1);
  \end{reduce}

load_package sfgamma;

load_package defint;

*** gamma declared operator 

int(1/(a+z^3), z,0,1);

reduce

$\displaylines{\qdd \frac{a^{\frac{1}{ 3}}\cdot \(6\cdot \sqrt{3}\cdot \atan \(\frac{2\cdot a^{\frac{2}{ 3}}\cdot \sqrt{3} - \sqrt{3}\cdot a}{ 3\cdot a}$
