If that was aimed at me, I meant discuss in private messages seeing as WE'RE BOTH DONE WITH THE SAME PAPER -__-

Everyone! How was paper 32? It was quite good for me. I couldn't do one sub-number, fortunately, it scored only for 1 mark. (It's the question that asks what happens to x if t was very-very large.)
I think the questions were quite simple, but the procedures were longer than usual.
How about all of you who took it?

Yes that was the only question that intrigue me. The rest, i'm sure of it.
But I think It also increases up to a point where it is bigger than 1 and becomes undefined.

how did you guys get the differential equation for that question? it was so confusing i just skipped it :(

The intergrate ones?? ahahahahhaa
You have to inverse both sides or you wont get the answer
1/ sinxcosx= e^(-2t)/-2

If you inverse becomes
sinxcosx=-2e^(-2t)

Then you can solve

Cant remember.lol. But the answer was pretty exact. No long decimals thing.
