I think I let that one through. Looking at it now it doesn't seem like
a great conversation starter but that's not really a criterion. I
wonder if it was created by an AI somehow or if someone spent a little
time crafting a vaguely believable but not quite sensical message.

If there is to be a new API then there are a *lot* of other things
that I would want to change about it compared to solve so it
definitely wouldn't
still just want to make a new solve
function that isn't compatible with any of the existing ones.

Hi all,
Following the previous release of SymPy 1.10rc1 a few days ago I
discovered a few problems with the test suite. Certain tests failed
under certain configurations depending on which other libraries were
installed.
I've since fixed these and so I have now released a second candidate

Hi all,
I've just released SymPy 1.10rc3 release candidate.
Following the previous release 1.10rc2 release candidate a couple of

It is wrong or at least useless since B(t) appears in the integral. A
correct and simple result is given by the 1st_linear hint:
In [111]: dsolve(expr, hint='1st_linear')

The SciPy implementation only works for floats. It should be possible

Hi all,
I have a new blog post following the last one:
https://oscarbenjamin.github.io/blog/czi/post2.html
This one discusses SymPy's polynomial system, improvements that can be
made and in particular how to make use of python-flint to speed up
polynomial operations in SymPy.

Hi all,
There are many spam messages being sent to the SymPy mailing list. So
far I and others have deleted and blocked these from the moderation
queue. I'm not sure what has prompted the sudden urge to promote what
look like Indonesian gambling websites on the SymPy mailing list but I
guess that
This is a bug. Can you open an issue with sympy on GitHub?
The correct answer is given if you use exact rational numbers (S(1)/2
or Rational(1, 2)) rather than the float 1/2:

I don't want to give the impression that I solved this much less that
I did so on my own. The DMCA emails were sent to Ondrej, Aaron and Me

I can't remember if I filled this out. Is the schedule already fixed yet?

Hi all,
I was looking at the SymPy docs earlier today and I found that it was
quite difficult to find the docs for the polys module. I'm interested
to know what people think about how the API docs are organised because
I see at least some problems but I'd like to know more from a user
perspective

Hi all,
I'm thinking about making a release of SymPy 1.11. Until now I've been
too busy at work to make a release but things are beginning to ease up
at the end of the academic year. We're already at the point where
we're getting new reports for bugs that were fixed months ago so a new
release

Hi Kuldeep,
I see that there is a proposal for working on probability in the ideas page:
https://github.com/sympy/sympy/wiki/GSoC-Ideas#probability
It is suggested there that Gagandeep Singh or Smit Lunagariya are
potential mentors. I have not seen much involvement from either of
these
