Hi,
Just a reminder, that all GSoC students must submit the mentor
evaluations, do it today (i.e. now), if you haven't done so yet.
Please make sure you do it, and also ping your mentor to submit it as
well. It is very important.
Thanks,

Great job! So lets finish the pull request with all this, write tests and
get it in. If somebody finds a mistake in sympy, we can fix it later. I
think that sympy is right too.

Derive it for j=1 m=0 m'=1 or 1 0. That's what I did. Just put these numbers

Hi,
Should we deprecate "ln"? NumPy doesn't have any "ln", neither does
Python's math library. Everybody uses "log". In sympy,
we just have "ln = log" anyway, so I am all for starting to return a
deprecated warning if people use it. And remove it eventually in later
releases.

I think we should do it as an option, yes. And we can start using it,
as an option and see how it goes.

I think it's essentially the same. However, if the cache is just a
dictionary, as it is now, then it is a *bad* idea. Here is some intro

Hi,
I am sharing some patch review tips, and I am interested in any
feedback. I look at my github notification page and see what new pull
requests were made, or what new comments were made. Then I open lots
of terminal tabs, and in each execute the following:
