C1, was a walk through the park, finished in 30 mins, tried to fall asleep..after a few mins had my hands together, an invidulator asked me whether i was praying ;] hopefully got 100UMS

 

[Hailstorm94]

nop :'(, what was the equation of the line L1 ? wasn't it somethingx 2y+45 ?

l1 was 3x-4y+15=0 l2 was 4x+3y-30=0

 

[Josh111]

length of line was root 160

yeah it was √160. you could have simplified it as √16√10= 4√10

 

[molybdenum42]

2 + 3root5 possibly first one
root160 line length
27,000 sum
n =21
points of intersection (3,6)
equation 3x -4y +15+o
graph moved left 2 and crossed y axis at 25?
y= (x+5)^2(x+1)
gradient of normal 3
k = 1/16, x = -1/4 and y =2/3
32 for one of the early questions
A = -6 and B =1
asymptotes at x = 0 and y=4
k = 1/3 or -1 (could be -1/3 and 1 can't remember)
x is between -1/3 and 3

phew can't remember anymore!! please reply people i need reassurance!! x

same as mine
but which 1 was 32 ?

 

[molybdenum42]

same as mine
but which 1 was 32 ?

it was 8^5/3
haha good! Can you remember any more questions?

 

[ahmed soliman]

yes correct and the first one was 2 + 3root5 not 4 because it was (8+12root5)/4
actually I am trying to remember what i got as c in integration but dont remeber

yes, right you are, that is what i actually got haha. I got c = -2

 

[ahmed soliman]

yes, right you are, that is what i actually got haha. I got c = -2

can u tell me what was the equation of integration because yet i dont remember and i am waiting for the unofficial marking scheme

 

[molybdenum42]

uuuuuummmmmm... -9x^-1 -6x + x^1 very unsure about that though, sorry

 

[ahmed soliman]

i got something like that but also not sure though but what were the (x,y) plz tell me

 

[molybdenum42]

(10,-3) i think

 

[molybdenum42]

then when i subbed -3 in i got 10 =12 + c so c = -2

How many marks was the question where the length was root 160? For that part only I mean

i think it was 2 or 3, no more than 4 for sure. Don't worry, doesn't sound too serious!

 

[ahmed soliman]

i got the correct equation in integration but wrong c due to calculations

 

[molybdenum42]

don't fret, that'd probably only be about 2 marks out of the whole question - maybe a method mark and an accuracy mark.

 

[Josh111]

when will the unofficial marking scheme be posted ??

if you go on student room at around 2pm (uktime) and type"" arsey c1 june 2013 paper" you should be able to see it.
Im not sure if it will be up around 2pm but I think it will be. It will defo be up by 6pm on Tuesday.

 

[ALevel96]

I will post all the answers in the morning pretty sure I have 100UMS
