Edexcel Core 3 - 21st June 2016 AM

did anybody get something like 0.1609 for Q5?

Thankyou! I don't know the exact mark for question 8b) but would assume it was 5 or 4 or something - I seem to remember a lot of the end parts of questions were 5 marks. Also, I thin all of 4a) was 5 marks.

Well it gave a range of pi/4<x<pi/2 if I remember correctly, and only the turning point for x = 0.9.... was in the range. If there were multiple solutions, the question would have said find the x-co-ordinates for the turning points (plural).
Having said this I doubt you will lose more than 1/2 marks for putting 0.106... or whatever it was

Question 9 was almost the same as the question 8 on June 2007, anyone noticed?

Was there a form for the normal? Will 2y + x = 35 lose a mark? Lol, I was thinking 75 raw...

Creds to
thesporkthiefNumber of marks for each question:
1) a: 4, b: 1
2) a: 4, b: 3
3) a: 3, b: 5, c: 2
4) a: 5, b: 2, c: 2, d: 2
5) a: 5, b: 5
6) a: 4, b: 5
7) a: 2, b: 3
8) a: 4, b: 6
9) a: 2, b: 2, c: 4

Thank you spork theif!!

I just realised how many silly mistakes I've made. If I've got the first part of a question wrong and worked out the answers for the subsequent parts of a question with the right methods would I still get full marks for the latter by ECF ?

yeah i remember!! i was doing the question an was like i swear this has come up before

Ah great They should accept either then because it did say "value" rather than "values"

Looking at what people have put, I'm feeling quite good about it all.

I do further maths and even though I am quite familiar with C3C4 etc, I'd ay this was harder than last year's, easier than June 2013.

Some of my answers I remember:

6, -5
a=6
x is less than -root5, x is greater than +root5
33.0 and 273.9 degrees
86.1 degrees
y=21 x=ln(5/2) k=25
0.1609
0.5cosec(4x)
A=3 B=4
y=-1/2x+35/2
-1.866 (think this was exact)
0.294, -2.848, -1.277, 1.865
6.74
a=5 b=2

Anyone get similar?

Unfortunately I'm pretty sure edexcel aren't liberal with follow through marks. Can be gutting, I know

Nah didn't ask for a form. I wrote it as that too, will be reet.

That is most depressing. Do you know how they award ECF marks?

didn't see original post but you may be getting some method marks, just not accuracy marks. if it is a 5marker then you might get 2-3.

It asked for the answer in the form y=f(x)
