no worries
Hi,
Say a question asked us to express something in terms of n
And we'd found k=(n+1)
Could we express the value in terms of k? I forgot to switch k to n+1 and was wondering if this would lose marks?
I thought that as k was a constant in terms of n then it would be counted as expressing the quantity in terms of n....or am I completely wrong and should deduct a mark?

I will have to get back to you as I am in the middle of doing FP3 solutions

Sure
Thanks
Sorry to bother you

4. Sorry the files do not fit in one post so they will continue into the next.

I though the paper was tough but worse it was very time consuming (I wonder how many people run out of time)

Q3 was a joke because it took a long time and would have messed up a lot of people ... I would have put it last
Q8 was also tough and also took me a long time/pages

I will try to revise my grade boundaries tomorrow

solutions continue into the next post

Wow I actually got the area question. Drooped 9. Shud be 96/97 i hope

Thanks very much for the solutions. If you've got time would you be able to tell me how many marks you reckon I've lost?

Q3: Came back to it late in panic and in the normalised eigenvectors I divided by 4 instead of 2; correct eignvalues and general vectors I think, and correctly followed into the next part.

The area proof: I drew the right angled triangle, started calculating the area but my algebra didn't come to a conclusion; ran out of time}

The focus proof: I went for pythagoras using (2costheta - root(3))^2 + (sintheta)^2 as one distance and (2costheta + root(3))^2 + (sintheta)^2 as another; I ended up, as was inevitable so I don't know why I tried it, with too many cos^2 and not enough sin^2 for any cancelling...

The very last part; I used factor formulae; messed up a factor of two somewhere to eventually end up with y = (-1/2m)x; I don't think anything was wrong with my method (I did sort of "assume" the line would be through the origin but that's because I saw that doing x/y would give me something very similar to my term for m)

I would imagine:

Q3: typically loses 2

Q6: typically loses 2

Q8b I only know the proof I put in my solution (as standard as it gets). I have no idea if the marking scheme would allow alternatives (which I do not know)
Worse case loses all 4

Q8c loses 2 (possibly 3)
I would allow assumption line goes through the origin id minimally justified
12. Any update for the grade boundary for fp3?

Do yoy have M1 previous grade boundaries Sir?
Are you a tutor btw?

will do that very soon, once I have a little think ...
I did the solutions early hours of the morning so I had no time to reflect on them.

Awesome, thanks
pretty sure everything else was correct and 64/75 should be serviceable in such an exam...

Without any in depth analysis and just off the top of your head, what do you think 51-53 out of 75 would be?

Hi, can you have look at mine as well please?
For the volume question, I think put down 2pi r^2 for the volume, i did all the calculation but I even forgot to times 4pi although that is wrong anyway, how much would I lose for that?

For the matrix question, i did one eigen vector wrong, the part c would be wrong as well, how much would i lost?

For the prove of area of the triangle one, I realised once the tangent is perpendicular to the x axis, you can form a right isosceles triangle and managed to get area 1 but i think that is the wrong method. how much would I lose?

Thank you !!
