Has anyone done an unofficial mark scheme?


I've got all solutions except the vectors one at this link, I didn't have the paper though

A =(1, 0, -1) don't remember B/C

I know that there were 4 parts:
(a) line through AB - don't remember the vectors for r=a+(t)b
(b) finding the plane, r.n=p and yeah, p=3 and i think n=(4,-5,7) or something
(c) intersection of plane/line? I don't remember
(d) yes, 1/sqrt(10) [d]

Thanks for your help - I'm quite happy with those boundaries.

I will revise the FP3 boundaries when I attempt the paper
Think I dropped around 13 marks, was so gutted to see two co-ordinate geometry questions though :frown:
Unofficial Mark Scheme (with questions):

I think I've dropped around 15. How many ums do you think that is?

Posted from TSR Mobile
What ums would 45/75 be.
what is the answer for the vector question?

will I get a mark for finding an eigenvector?

This is a bit vague?! Do you mean instead of the normalised eigenvector?!

Most likely for (b) you will, but you won't lose any if you normalised for (c), as this was required P was orthogonal
