Sometimes whilst doing C1 and C2, I can do the most complicated yet the most difficult questions like integrating to finding obscure areas under weird graphs/curves, but when it comes to basic **** like adding and subtracting I usually **** up completely, and proving stuff which is so easy, like that screwed up question on Sum of a infinity to 25 or some stuff like that, which i could've done with my eyes closed, if i understood what the bloody question is asking. I probly lose marks that stupidly.

I agree, I can do such silly mistakes such as forgetting about negative signs and that can mess up the whole answer.

It really gets on my nerves. It's especially worse with M1 as then you tend to forget to convert into grams/kilograms/Newtwons etc...

Hello!

If you used the values x=0 and x=2 (at least I think that the x co-ordinate of A was 2) in your integral, it gave you the area under the curve between the y-axis and A. If you then found the y co-ordinate of A, that gave you the height of the triangle. The area of the region R was the area of the triangle (from x=2 to x=3.33333etc, so the base is 1.3333333etc and the height was 16). Adding the area of the triangle to the integral gave you the area of R. Or at least I hope it did...

Got to admit, the paper is quiet easy... more easier than i would've thought... Even though I arrived 10 minutes late to the exam, I finished in time to check all the questions for the second time and make sure I have gained the easy marks...

Now I just have to hope I either caught or avoided all the careless mistakes I usually make. Not much chance of that one... :rolleyes:

Ah. I think I'm just being a bit slow today. My bad. (stick to the maths danniella, it's more within your capabilities than sarcasm at the moment... )

OK... now that C1 and C2 are over, what are you guys revising for... I still got mechanics in few days and been trying to do some past papers... mechanics requires more concentration than C2 and I couldn't seem to be able to get my self to do it... any thoughts?

It would be hilarious if you didnt, you could've easily dropped a minus sign forgetten to put a c on the second last question. Theres being confident you've done well and being overly confident. I hope you didnt tell anyone in real life you were gonna get 100% because seriously you'll look like total fool people dont forget things like that.
