Note: 
changed: The link to the tutorial by Martin N. Dunstan doesn't work (http://www.dcs.standrews.ac.uk/~mnd/documentation/axiom_tutorial). I can't find this tutorial elsewhere. The link to the tutorial by Martin N. Dunstan doesn't work (http://www.dcs.standrews.ac.uk/~mnd/documentation/axiom_tutorial).
Most introductory material about Axiom applies to FriCAS. The Axiom Volume 1: Tutorial is available in printed format at http://publishbook.com and http://www.lulu.com/product/filedownload/axiomvolume1tutorial/243127
On this web site you can enter FriCAS commands and see the output in proper mathematical form. These commands can also be typed directly into FriCAS installed on your own computer.
You must enclose each set of FriCAS 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, FriCAS processes the contents of each section you have marked and the FriCAS output is displayed.
Try this command:
[1/7,3/4, 5/6]
(1) 
Please feel free to play with this in the SandBox!
Let's see if we can perform a finite window Fourier inversion.
simplify(integrate(exp(%i*_\omega*t) * exp(%i*_\omega * _\tau),_\omega=_\Omega .. _\Omega))
(2) 
Try this integrating this
2*x/sin(x)^2
(3) 
integrate(%,x)
(4) 
Now differentiate it
D(%,x)
(5) 
simplify(%)
(6) 
Expressions (3) and (6) are really that same.
simplify(%%(3)  %%(6))
(7) 
D(x^x,x)
(8) 
See, that was easy!
Here are some more things to try.
integrate(log(sin(x)),x=0..%pi)
(9) 
limit(sum(1/i^2,i=1..n), n=%plusInfinity)
(10) 
Can you explain these results?
