Coordinates were :

(-80,40,140) or (-80,140,40)

Cant remember which way the 140/40 go. - My maths teacher did the paper today and showed us the answers .
My coordinates looked much more like those! Thank God

Thanks for the reassurance

Np mate

I could bring in the paper + answers if anyone wants me to

i think it is (-80,140,40) as i remember the z co-ordinate of A was zero and the direction vector multiple was 0.4 and z co-ord of AB was 100

Np mate

I could bring in the paper + answers if anyone wants me to
and that would be most appreciated

Did you go through the question in the comprehension which asked you to sketch that graph? I really want to know whether I'd get the 2 marks for this (can't remember all the points and the inequalities).

We only went through the question paper tbh, I will ask tomorrow though since its bugging me too! - I did the same to what you did
8. To everyone else - I will get it for tomorrow
9. Just me who just did a straight line for that graph question?

Perfect, will definitely get the marks. I think the 2 marks will be 1 for the step function 1 for correct labelling so you will definitely get 2

did they label it for us? I cant remember

It was SKETCH not PLOT, two completely different things
14. Were we supposed to put numbers on the axis for the step graph. I thought it was just a sketch so I just did roughly even lines, evenly spaced.

I think a sketch in this case (because it's such a deviation from the simple y=x^2 sketches we usually draw in core maths) still needs key data like all the points and values to be there. A plot will have all that but be correctly spaced out (i.e. correct proportions).

Not quite sure whether the numbers were absolutely necessary. There were 2 marks available so 1 might have been for that. win2kpro has promised to get a copy of a "teacher mark scheme" tomorrow, so we'll get some more clarification then hopefully.
17. Here is the first paper for you!

personally I think I dropped marks on:
7(iv) not taking away my answer away from 90 degrees
The graph on the comprehension, and the last question, i forgot to multiply by 100 so i got mm rather than 10cm

+ I always make many silly errors

Oh I've flopped that graph then...
What I did was I picked a midpoint for each interval and plotted a point for each, then drew a line... and for the second part I said it had a positive correlation(plus I also said as the annual passengers increase, so do the number of trains,etc.)
I did the same. Just plotted the mid points

Would we get any marks for that?

I completely understand where you are coming from mate. I need an A* to get into an imperial so i have to feel like i have made no mistakes at all to get 90% cos i know that i will drop several marks through silly mistakes however well i think i have done. It is worse in C3 i find.

Lucky for me all my answers match up with the general cosensus in this thread so i am pretty confident. My dream of imperial is still alive, just.
