This question has ben around some time, I do not think that we get more feedback than that. So I have accedpted the only answer (it is at score 9 now).

@quid I suppose in this case the removal of the tag has to be done manually. (There are 30 questions in this tag.) Or do you think that merging calculus-identities into calculus could work for some part of those question? (In this way we would reduce the number of questions that are going to be bumped.)

@MartinSleziak I think a reasonable proportion can be merged; merging is easy enough. I'd remove from those where calculus makes no sense at all, and merge the rest. If you would do the first, and ping me, I could do the second rapidly.

Thanks for the response. I'll try to do some retags. (As much as I can - I have limited internet connection now.)

@quid Maybe for some of them it is a stretch, but I'd say that the remaining questions either already have the (calculus) tag or it can replace the (calculus-identities) tag: math.stackexchange.com/questions/tagged/…

There are now 12 questions tagged calculus-identities and 7 of them do not have calculus tag.

These are relatively small numbers - probably the retagging can be finished manually, at least if there are some other possible improvements to those posts.

Still, merging would save at least a few bumps.

Thanks, I think it's fine, I merged @MartinSleziak

Thanks!
