Hi Alex,
By the way, I think this is a good moment to advertise for a very good idea
Nicolas had a few years ago, that is to implement and use the very common and
basic notion of family:
A Family is an associative container which models a family
`(f_i)_{i in I}`. Then, f[i]

I am surprised by the following:
sage: s = set(['a', 'b', 'c'])
sage: repr(s)
"set(['a', 'c', 'b'])"
sage: str(s)
"set(['a', 'c', 'b'])"

Dear developers, I looked into sage/symbolics/expressions.pyx and the
definition of simplify_trig().
This funciton applies trigsimp and trigexpand from Maxima and as a
result,
sage: (tan(3*x)).simplify_full()
gives terrible result
(4*cos(x)^2 - 1)*sin(x)/(4*cos(x)^3 - 3*cos(x))
Despite the fact

This is the pprint (pretty print) module. From ipython's man page:
-[
Did anyone notice that the plot scale sometimes does not contain any
number or sometimes only contains one number? Unfortunately I have no
simple example to reproduce. But its not a problem with too small or
too big numbers.
I think the plot function should guaranty that at least two numbers
are

Just to clarify, the option "-pR" is no
If you look on the thread
" Do we need "cp -a" - or would 'cp -pR' do ?"
you may have noticed that Gonzalo Tornaria has discovered that
"local/bin/python" is a hardlink to "local/bin/python2.6". From what I
understand, this is the only hard link in Sage. It would be better if
this could be repl
