Re: [sympy] Re: Who can mentor for GSoC?

Hi all, The projects list for SymEngine( https://github.com/sympy/sympy/wiki/GSoC-2016-Ideas#detailed-subprojects-in-symengine) has updated with a few more projects. I request all to have a look. A lot of can be done on presenting more details to the ideas present in this section. I request the

[sympy] A dedicated bug fixing project in GSoC

Hi all, I was discussing this idea with Ondřej the other day. Before putting this idea in the wiki, I wanted to discuss it here. Every year, some organisations have a dedicated bug fixing GSoC project. The main aim here is to tackle and close off as many issues in the issue tracker as

[sympy] Would anyone like to clean up the GSoC Ideas Page?

Our GSoC Ideas page has become quite the document over the years and we submit essentially the same thing each year. We did not get accepted last year as a mentoring org. I think that we need to revamp our application so that it shows a breath of fresh air if we want to have a chance of getting

Thanks a lot Harsh, for the suggestions and reviewing the ideas. After going through many issues ,I found that the main issues on trigonometric are https://github.com/sympy/sympy/issues/10217 and https://github.com/sympy/sympy/issues/9824 (nested expressions) and right now solveset can't

[sympy] Definite Intergral wrong. How to solve

Hi, How to get the correct answer for the problems 1. Integral( (1+x**2)**(-3/2) ,(x,-1,1) ) 2. Integral( (1+x**2+y**2)**(-3/2) ,(x,-1,1), (y,-1,1) ) Both gives 0 in sympy which is wrong. Mathematica gives correct answer! Nasir -- You received this message because you are

[sympy] GSoC 2016: Step by step expression visualization.

Hello! I'm Keval and I'll be applying for GSoC this year. After going through the ideas page, I found Step-by-step Expression Visualization project very interesting and practical for improving SymPy

[sympy] Looking for a Good First Bug!

Hi guys! I'm a new contributor, and I've just finished setting up my development environment for Sympy, and am comfortable with the development workflow (I have no issues with git...yet ;) ). However, while looking at "Easy-to-fix" bugs, most are already solved, or so old that deprecation has

Re: [sympy] Looking for a Good First Bug!

Barun, If the easy to fix bugs are solved they should be closed. You can show that the bug is no longer relevant and report that in the issue requesting it to be closed. That would be very helpful. Jason Jason moorepants.info +01 530-601-9791 On Sat, Feb 13, 2016 at 10:18 AM, Barun Parruck

Re: [sympy] Re: Rewriting expressions as a Meijer G-function for integration

I've been thinking about this same topic a lot recently (partially due to a question about a G-function form of tanh), and it seems like the more generalized G-function you mentioned, Ondrej, is probably necessary at some point. There doesn't seem to be a whole lot of literature on these

[sympy] Re: GSOC 2016 Series expansions

Hi, Last year I implemented Formal Power Series and limits of sequences. The algorithm described in the paper is almost done. You can see the XFAILED tests in series/tests/test_formal.py and series/tests/test_limitseq.py, they can probably be made to pass. On Saturday, 13 February 2016

[sympy] Point in infinity

Hello! How one could start with implementing a concept of point in infinity or line in infinity? It would be helpful for everyone who tries to use projective geometry. Without point in infinity, it is impossible to define reflection with respect to a circle of it's center, to exemplify. If it
