Here's my problem (mathematica 5.0,5.1,5.2):
Limit[Coth[xB], B -> +Infinity]
it doesn't understand.
mmh. ok I try then:
Limit[Coth[x B], B -> +Infinity, Assumptions -> Im[x] == 0]
WRONG ! In fact:
Limit[Coth[x B], B -> +Infinity, Assumptions -> Im[x] == 0 && Re[x] <
Indeed the correct result should be sign(x). And I couldn't find a way
to get it right.
Do I mistake something?
Thank you in advance,
