C1 & C2 discussion - Jan 2013

I think my inequality was -2 < x < 6, haha. Oooops again.

noo its right -2 sry im not sure i think 2 or -2 forgot

 

[yayifications]

noo its right -2 sry im not sure i think 2 or -2 forgot

Haha, let's hope it's -2 then! I think we've analysed every bit of the paper now haha. As long as I get more than 83 UMS (what I got last time) I'll be happy - even if it's only 84!

c1 was not that of a hard paper but c2 was way easier
my only difficulty was due to a silly mistake in question 11 (a) i guess ( the one with differentiation ) i had a calculation problem
so i just wanted to ask if my steps were correct but made a mistake in calculation
thus final answer in part a was affected which inturn affected part B and C
but the steps in B and C are correct but answers are wrong because they are related to part a
am i going to lose the mark of the full question or only the mark of part a ?
thanks in advance

guys does anyone remember the derivative equation used to find the point Q was it 1-2/sqrt(x)? or smthn can someone post it

dude do u remember the derivative used to find the point Q i forgot what it was the one we used to equate to 3/2

If for question one on C1, I took -x out of the brackets so I ended up with
-x(2x-1)(2x+1) would I get any marks? Cos it does expand to give the right answer, but I realise now that the best way to do it would be to take x out, not -x :/ I recognised that it was DOTS, just went for what I thought was an easy route :/

 

[Cell_ar]

Anyone remember what they got in C2 for the shapes question. the areas and perimeter.

 

[Hamzeh S]

Guys Equation of the derivative to get point Q what was it :S ?

 

[Beedo]

Anyone remember what they got in C2 for the shapes question. the areas and perimeter.

circle with a triangle inside

 

[Cell_ar]

circle with a triangle inside

yeah you remember the answers? b) was area of major sector c) was perimeter of something and d) was the area of that something xD

 

[I am not a robot]

Do you reckon I'll get any marks for q1?

anyone ???

anyone ???

You would Lose each accuracy mark, but would still get each method mark, so you'd lose another 2 on top of part A (I think) Could you read above what I did for q1 and see if I'd get any credit?

 

[Abdul Faiz]

does anyone remember a question about are with answer 49/4 plz remind me of it

Yeah, the area of the triangle is 49/4, you will get base as 7 and height as 7/2, its 49/4!!

 

[Abdul Faiz]

Guys for the integeration questions what did you get for c ? was it -7 or 7 ? forgot which one

its 8

 

[I am not a robot]

Yeah, the area of the triangle is 49/4, you will get base as 7 and height as 7/2, its 49/4!!

That's what I got! Do you know if I'd get any marks for my answer to Q1? (see above)

 

[I am not a robot]

its 8

I got 8 too! Really starting to think I got everything apart from q1 right :/

what was the question i forgot if i see the question ill be able to clear ur doubt
and btw do you remember question 11 was out of how much ?

 

[Hamzeh S]

guys whats the equation of the derivative used to find point Q ?

 

[Alla' Abu-Sultaneh]

In C1, does anyone remember how many marks were on the last question? and on the last part of the sequences question, which was finding Q?
