I have to find the limit as stated in the first line and my working is below but I'm unsure of how to continue

I could not figure out from the first two lines how tan2 t managed to become t (1 - cos 2t) / 2.
Maybe I missed out something.
What I would do is to rewrite tan2 t as sec2 t - 1 because sec2 can be easily integrated.

sorry for the bad handwriting but the first line is integral of tsin^2t
Oh, my fault. Will submit a response only if I can solve it by tomorrow's 2 am.

Here are my workings for this question, which are probably wrong.
Perhaps my brain is fried. Because my signages went slightly different from your workings in lines 5 to 7 and thereafter.

A lot easier to use L’Hôpital’s rule first (fraction is 0 over 0) then after that rely on the fact that if you differentiate an integral, you get the integrand back..
