I think Dima very very confusingly actually agreed that this is a bug in maxima that is in the newest version. I think your options are: - use the sympy option, or - fix the bug in maxima, or - change what sage uses by default, or - wait On Sun, Jan 22, 2017 at 12:49 PM Peleg Michaeli w

So... I couldn't really follow: should I open a new ticket, or should it be solved by integrating the new maxima? On Sunday, 22 January 2017 19:37:50 UTC+2, Dima Pasechnik wrote: > > > > On Sunday, January 22, 2017 at 4:13:53 PM UTC, William wrote: >> >> On Sun, Jan 22, 2017 at 7:14 AM, Peleg Mic

[sage-support] This limit seems to be wrong

2017-01-22 Thread Peleg Michaeli
Hi, sage: ((2^(2*x+1)+(2^x*x^100)^(3/2))/(4^x-100*2^x)).limit(x=infinity) -Infinity This is a wrong answer. It should be 2. Replacing 3/2 in the power by 1, 2, or 3 (at least) gives correct answers (2, inf, inf). Replacing it by 5/2 given a wrong answer again. Is this related to a known bug?
