Fixed in 13.3.1 or earlier. Limit[Log[2 - Sin[x]*Cos[x]], x -> Infinity] outputs Indeterminate and MinLimit[Log[2 - Sin[x]*Cos[x]], x -> Infinity] // FullSimplify results in Log[3/2] and MaxLimit[Log[2 - Sin[x]*Cos[x]], x -> Infinity] // FullSimplify performs Log[5/2].

Limit does not in general find the tightest possible interval for functions that oscillate.

| Jan 14, 2015 at 18:59 | comment | added | Szabolcs | @user64494 The idea is that the tag should not be added by the person who posts the question. When appropriate, it will be added by others. Please read the link I posted. While here the situation is pretty clear, the majority of bug claims on this site turn out not to be bugs. | |

@user64494 Most or all of those 500 questions were vetted by the community first before they received the bugs tag. The tag description (mouseover the tag) mentions that as well. Anyway, Limit[Sin[x]*Cos[x], x -> Infinity] is a simple example of the bug.

| Jan 14, 2015 at 17:39 | comment | added | Jacob Akkerboom | Posting here as in addition reporting the bug to support is also a very nice option in my opinion. | |
| Jan 14, 2015 at 17:36 | comment | added | user64494 | @ Szabolcs: I see about 5 hundred questions tagged bugs in the forum. | |
| Jan 14, 2015 at 17:31 | comment | added | Szabolcs | @user64494 This is not an official Wolfram site. We are just users like you. It's better to report bugs to Wolfram, to make sure they have the chance to fix it. That will benefit everyone. | |

| Jan 14, 2015 at 17:26 | comment | added | user64494 | @ Szabolcs: Thank you. I have not known about Wolfram support. Maybe, some modification of the code gives the right answer. BTW, I inserted the bug tag, but forum changed to bugs. | |

| Jan 14, 2015 at 17:25 | comment | added | Szabolcs | Regarding your last edit: Please do not include the bugs tag when you post a new question. It will be added after the community confirms it as an actual bug. meta.mathematica.stackexchange.com/q/354/12 | |
| Jan 14, 2015 at 17:24 | comment | added | Szabolcs | If you are looking to report a bug, please contact Wolfram support directly. What sort of workaround are you looking for? | |
