Hi and thanks both for your replies. xreplace doesn't look like
something I'd be interested in using, but as a very superficial
approximation, it looks like replace changes the expression
lexicographically but subs changes the expression mathematically. I
know I know that's *very* superficial but I

It's just an optional setting so there is n
Hi there,
today I stumbled on a trigsimp problem:
In [4]: trigsimp(cos(x+y).expand(trig=True))
Out[4]: -sin(x)*sin(y) + cos(x)*cos(y)
In [5]: simplify(cos(x+y).expand(trig=True))
Out[5]: -sin(x)*sin(y) + cos(x)*cos(y)
In other words: the identity
-sin(x)*sin(y) + cos(x)*cos(y) == cos(x+y)

I observe that SymPy Live is able to output properly typeset math
expressions (like we have on math.stackexchange.com) presumably using
MathJax. I would most appreciate whether it is possible for me to get
such a display on my computer. Both the regular and pprint display are
not so convenient for

Thank you very much! I have backported the late
Even with the older IPython, using the SymPy version is preferred
(assuming you are running the newest version of SymPy, which you
should be). We technically haven't tested it on the older versions,
but it should work just the same.
