The questions themselves i don't think were that hard.
It's just the time... some of those questions made you work for the answers.
had 12 min to do last 2 questions....

If they didn't specify to give an exact value-would you still lose marks for giving decimals

Decimals should be fine as long as they're accurate to 3 s.f.

How many answers did people get for tan@=-1/3

I only got two but apparently it was four :frown:

another one makes a rookie error, tut tut.

Everyone makes mistakes, you don't have to be so ignorant to other people about it though dude.

I think you forgot to do 1 over your gradient. It gave you the equation in the form x=... And you had to find dx/dy and then flip it, so 1/24 pi was the gradient. Or at least that's what I got

shut up kid

smd

ahahahahahahhahahahahahahahahahahah to that idiot who says boundaries for 90 ums is 73 hahahahahahahahaha

what paper did u sit? c1?

Original post by big fat poo

Mate I totally agree with you, like that paper was p*** easy I could have done that while asleep. Actually I could have done it while doing C4 too, that's how easy it was.....STFU^^ and GTFO

i hope ur not being sarcastic, people don't realise how easy this paper was. Many uni offers will be missed. peak times.

get your extenuating circumstances ready.

Original post by Kabulkid

its ln(2)/40 please refer back to simple logarithmic core 2 knowledge before you attempt core 3.

Dont give me that, please sort out your arrogance before you attempt c4

dunno bout 100 but:

A* - 66
A - 61
so on..

Original post by dandroff

wat u get for lambda

Ln0.5/-40 ??

Arsey is an OG
He uploads maths papers with worked solutions, should be up in a few hours.

He sounds like everything i ever wanted :')

How would i know when arsey is done?

Original post by Drakton15

Pretty sure it's right. ln(0.5)/-40 = ln(2)/40, which is what I got

Yeah, it asked for a and b as an integer so it is ln(2)/-40

I'll go:
74 - 100
67 - 90
60 - 80

now thats impossible! 4 marker involving tan is 2 answers only. tanx=-1/3!

those are 2 solutions

yeah.... ur new here.

BFP=big fat poo

right with the last log question, I got up to xln2 = ln(10-0.5x)

I had no idea how to get ln(10-x)/ln2 - 1

wtf?!?!

Therefore, the rage of g? No wonder g(x) was so messy to work out, look at that range of rage.

Original post by Tina.Shaban

It asked for integers so I got ln2/40 I think

Absolutely. That confused me for a bit. I was like, how can 1/2 work if it isn't an integer? :s-smilie:

:s-smilie:

Original post by subject1

I predict:
75-100
71-90
66- 80
61- 70

Much easier than previous years. Basically if you make a silly mistake then no 90% for you!

You're crazy, I've been getting 95-100% in every maths exam I've done and this was harder than most bar June 2013
