integration..q below

Answer 1

\[\int\limits_{?}^{?} \frac{ 1-t ^{2} dt}{ t(1+t ^{2})-(1-t ^{2}) }\]

Answer 2

u=1-t² seems to be even worse than it is now.

Answer 5

Good advise:)

All I can say that if the integrand was a general term of an infinite series, then the series would easily diverge by comparison test (coming down to 1/t).

Answer 6

well..this is what i got at halfway through a problem..i was stuck here that's why i put this part alone ...

Answer 7

can't this be simplified in some way..?

Answer 8

i found another way to do the question but couldn't simplify this still!!
