[sympy] Idea for GSoC 2021

First of all, I know it's a little late and I haven't submitted a pull request; I've been trying to do so, but I haven't been able to solve any of the issues yet. So my first question here is if it's possible to be accepted without having submitted the pull request? Surely, I have learned to us

What version of SymPy are you using? Those both evaluate for me as expected in 1.7.1. Aaron Meurer On Thu, Apr 8, 2021 at 1:30 PM 'Bruce Allen' via sympy wrote: > > Dear Sympy developers, > > This is not a serious issue, but I wanted to flag it. According to the > documentation (and IMO correct

[sympy] behavior of asec()

2021-04-08 Thread 'Bruce Allen' via sympy
Dear Sympy developers, This is not a serious issue, but I wanted to flag it. According to the documentation (and IMO correctly): acos(x) = asec(1/x) So I was surprised to see the contrast between: >>> acos(Rational(1,2)) pi/3 >>> asec(Rational(2,1)) asec(2) I would expect the previous lin

Some CI to ensure the notebooks run is rather important, otherwise we'll end up with a bunch of broken notebooks over time. That's what happened with the pydy/examples folder. Lots of stuff was dumped in there over the years, but no CI to double check it actually runs. Setting up at least CI in th

One of the benefits of having sympy-notebooks as a separate repository is that we don't necessarily need to worry about those things. I would be in favor of just merging things into sympy-notebooks as long as they look OK. We don't need to apply the same standards as the main repo, or at least that

Using one of the jupyter<->sphinx tools is really nice for this. I've been moving the pydy examples to work with jupyter-sphinx and you get these results: https://pydy.readthedocs.io/en/latest/examples/carvallo-whipple.html (people can look at the rst source, download a notebook, or a py file and t

I don't think that we can utilize sympy-notebooks repository properly unless we figure out how to test out the notebook outputs, integrate with sympy releases, matching version compatibility, and link with documentations. Setting up this workflow is important, and once this workflow is set, I t
