What was the comprehension section about? I haven’t seen the paper, so it’s a genuine question.

What did people get for x coordinate where gradient = 1??

4.9172 or smth like that

Thanks.
Does anyone rememebr the integration by substitution question

C=1
I'm cooked 😅 comp was monstrous, and there wasn't enough time to do 8b, the last question on 7, and finish the Newton 4 marker
what did people get for the last 8 marker

Integral of x/x+1 where u=x+1 with boundaries c+4 and c and to find the value of c
how did everyone do the newrton rapson one? mt mind went blank i didnt know which x value to use or what do put for xn starting value

i got the angle was something like 3/4 pi and 4/5 pi
and then put it back into x and y

Differentiate to find f'(x) and then plug into Newton Raphson formula. Then just choose a starting value close to the first positive root like 4

I’m so glad I revised for it. That’s what I got.

did u differentiate 1/x - cosx
That comp killed me. I had to just guess. I crossed out so much! For the subs I used made t -3 and 1
We’re there 4 coordinates for the 8 marker

what were your x coordinates for the 4
what were your x coordinates for the 4

i got something funny for one 4+root 3 / 2

Yeah, I got x co ords 2+- √3 /2 and two points at x =2
what were your x coordinates for the 4

2,2,1.smth and 3.smth
