Hi all, it looks like that that stats package is not functional in the live
shell, why this?
Cheers

Having seen expressions that are hard to simplify into the same form, I'd say
that it has a place in SymPy (there's even a utilities directory). That said,
I'd probably suggest a name like nequiv similar to nsolve.
Cheers,
Tim.

Hi Juergen,
By live shell do you mean sympy live or any python shell?

Hello Aditya,
I have already setup the environment as given on the github wiki page and
just wanted to take this opportunity to introduce myself.
That's great! You should start working on issues to get yourself
acquainted with the codebase.
Hi,
I am a Computer Science undergrad pursuing my degree at BITS Pilani
University, Goa Campus, India. I am proficient in python and have an
interest in mathematics. I would like to contribute to the sympy project.

I made this function to test for the equivalence of two expressions. It
doesn't really prove anything, but if the tests are many, the probability
of it being wrong becomes negligible. Do such utility functions have a
place in SymPy?
def equiv(a, b, ntests=15):
Test if expression a is
At that point in the routine we know the expression is constant so either
it is zero or it is some other constant. So a set or random values for
symbols is computed and if it is *not* zero we have an answer, otherwise we
have to work harder to try *prove* that it's zero.

I think live.scipy.org doesn't exist. Probably you are referring to
http://live.sympy.org
import script.stats as st
If you want to import stats module, you should import it like this:
import sympy.stats as st
I hope it helps.

Doesn't expr.equals also do something similar to this?

Hello,
can someone please tell me how should I go on understanding the current
Risch Algorithm implementation. The docs doesn't explain the algorithmic
details and also in the free version of Manuel Bronstein
Take a look at https://groups.google.com/d/msg/sympy/bYHtVOmKEFs/UZoyDX81eP4J.
Nothing has changed since that thread was written (I should really
write this up on the ideas page).

Executing
import script.stats as st
Would result in an unknown module error
Any ideas?
Thanks in advance

I'm unclear what this line is doing
https://github.com/sympy/sympy/blob/e015652bf34987128bca3176d1c939fbd0d486cf/sympy/core/expr.py#L613.
It looks like it evaluates it, at least in some cases.
Probably Chris Smith could give a more definite answer.

No, that uses symbolics (thus it is not able to check complex
expressions or it will be slow).
Btw, you already asked this exact question here:
