C1 amazing exam!!

[sylvie3]

How did you all do?

 

[Madness]

it was really easy, what was the answer for the sequence question ?, the equation of the like that passes through 2 points

it was goood u ?

How did you all do?

for the fx thing which one do we take to intergate f'x or f''x ???

 

[sylvie3]

For the sequence question of 52 weeks i divided this section into 2 parts first i took the total of 21 weeks and then the total of 31 weeks and added them together because n was 21 and after 21 weeks the difference is changed into 600, for the equation of line i dont really remember the answer

We always integrate the first part which is f '(x)

actually, I took total of 21 weeks with difference 20 then total of 31 weeks with difference 0 because the question said that they continued to make 600 in the next weeks which means that there is no difference in the 31 weeks then i added them up

 

[sylvie3]

yeah there was no difference the equation was un= 600n, and i ended up adding them together and got a long number i guess most people messed up in this question

the answer was 27000 as i remember
inequality part a)x>-1 ?????

 

[Raiyan]

It was good but i feel like i am gonna miss out on A* :/

you have to take f'x

That's exactly how I did it
I got 27000 as the answer for total (last part)

how about the last questions guys? last 2 was pretty tough
What is the equation for the asymptote of the curve? The curve's equation is 3/x+4
Also how did you find the equation for normal? was the gradient of normal -x/3?
Also how about the equation which said the curve of the equation has equal roots?
how much did you get as k? I got 1/16, yet could not solve the equation

 

[Foreverfly]

my gradient of the normal was 3. i inversed -1/3. i also got 1/16 but you need to substitute it, into the simplified equation then multiply by 16. then you find the x value and sub it into the first simultaneous for the y value.

perfect !!!!!! the asymptote equations were x = 0 ,y =4
what about inequaities part a)x>-1

 

[ahmed soliman]

but gradient was 3

 

[Foreverfly]

what did you get for c? the integration question. i got c = -2.

 

[Madness]

what did you get for c? the integration question. i got c = -2.

same here

 

[Hailstorm94]

for sequences i got 324k.. since i took that after 21 d was 600... u guys sure there was no difference after that?

 

[ahmed soliman]

length of line was root 160
