alekz: do you know if anyone ever created a sympy cheat sheet? [10:46am]

I don't think we have one, but I think we should. It would just be one or two pages of a down-and-dirty reference to common functions and tasks, like:
powsimp(expr, deep=False, combine='all') - Combine common bases and exponents in an expression.
nsimplify(expr, constants=[], tolerance=None, full=False) - Find a simple formula that numerically matches the given expression.
etc.
For example, here is a LaTeX cheat sheet: http://www.stdout.org/~winston/latex/
and here is a Maple cheat sheet (PDF): http://math.mtsac.edu/resources/maple11_cheatsheet1.pdf
What do you think?

That is an excellent idea. Let's do it.

Sage has nice quick references:
http://wiki.sagemath.org/quickref
This one is for me vim cheatsheet (the nicest one I have ever seen)
http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html
e.g.
type expr .as_coeff_terms() .as_numer_denom()
Atom
Rational
Integer
Real
NumberSymbol
Symbol
Add
Mul x/y (1, (x, 1/y)) (x, y)
Power
Function
Integral
etc... but filled in with pertinent expressions.
Perhaps organized by topics like
introspection
transformation
...?
