Be prepaired for high thresholds. Vectors was easiest ever
-
what variant?

what variant?
I think variant 1 waz easier dan 32,which is da opposite of 2009...
-
I took 32, have no idea how easy 31 is.
Are we allowed to discuss it yet? I can't wait to do it!
-
Vre supposed 2 discuss it after 24hrs, dat is 20hr remaining.. :)
-
I took the paper 7 hours ago :P
-
i took paper 33
still ok but i do some mistakes
-
There's paper 33? I just knew!

i did it too! let's discuss D:
-
i took p32, was pretty good =D alhumdullilah.

NO DISCUSSION UNTIL 24 HOURS HAS PASSED.

NO DISCUSSION UNTIL 24 HOURS HAS PASSED.
thats exactly why nobody's discussing

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?
-
thats funny.. every1 i kno that took it said it was the hardest p3 exam from 2000..
even the nerds in my class said to expect very low thresholds

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

oh.. i didn't inverse anything :[
so what's the final answer?

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