Edit detail for AxiomTutorial revision 3 of 3

The Axiom Volume 1: Tutorial is available in printed format at http://lulu.com

• There is a good introduction to Axiom by Martin N. Dunstan, in English, at http://www.dcs.st-andrews.ac.uk/~mnd/documentation/axiom_tutorial
• a complete introduction to Axiom by Daniel Augot, en Français, is available at http://www-rocq.inria.fr/codes/Daniel.Augot/axiom_intro.pdf
• an Axiom tutorial and a collection of exercises by Christophe Conil and Quentin Carpent at http://la.riverotte.free.fr/axiom
• and a blog by Alasdair McAndrew containing an excellent introduction to Axiom.

A Quick Tutorial

On this web site you can enter Axiom commands and see the output in proper mathematical form. These commands can also be typed directly into Axiom installed on your own computer.

You must enclose each set of Axiom commands in a \begin{axiom} \end{axiom} section. For example:

    \begin{axiom}
    [1/2, 3/4, 2/3]
    \end{axiom}

When you save the changes you make to a page, Axiom processes the contents of each section you have marked and the Axiom output is displayed.

Try this command:

axiom
[1/7, 3/4, 5/6]

(1)

Please feel free to play with this in the SandBox!

Advanced Examples

Let's see if we can perform a finite window Fourier inversion.

axiom
simplify(integrate(exp(%i*_\omega*t) * exp(-%i*_\omega *
_\tau), _\omega=-_\Omega .. _\Omega))

(2)

Try this integrating this

axiom
2*x/sin(x)^2

(3)

axiom
integrate(%,x)

(4)

Now differentiate it

axiom
D(%,x)

(5)

axiom
simplify(%)

(6)

Expressions (3) and (6) are really that same.

axiom
simplify(%%(3) - %%(6))

(7)

axiom
D(x^x,x)

(8)

See, that was easy!

Here are some more things to try.

axiom
integrate(log(sin(x)),x=0..%pi)

(9)

axiom
limit(sum(1/i^2,i=1..n),n=%plusInfinity)

(10)

Can you explain these results?
