Divergent integral simplifies to -1/4 with simplify_sum

Thanks for the update!

Good questions. I'll pass them on, but obviously if not all commonly used lisps can use this it would have to be modified or discarded.

But sometimes it doesn't break handling unicode - and if the LANG environment variable doesn't end in utf8 what does SBCL do? SBCL outputs utf8 only if that variable tells it to.

Sorry for possibly creating the ticket in the wrong category, I don't use Sourceforge too much for new tickets. Though I guess it's not really a bug, so maybe it is indeed a feature request?

Slight Unicode update for integrals and related

Context - agreed! I just noted that Sympy considers the cases n=0 and not zero separately, so I considered the Maxima behavior a bug, and was trying to declutter.

Great, thanks.

Probably debatable (the accumulation function when n=0 clearly doesn't have any singularities (discontinuities?), removable or otherwise), but here is the actual original report: declare(n, integer); integrate(cos(2 * %pi * n * t), t, 0, 1); This returns zero, and that certainly is a bug.
