Edexcel FP3 - 27th June, 2016

The only question I'm not sure on is the last one I think I did everything right but can't seem to remember my answer. The position vector was (0,-0.2, and something else )

my honest opinion is that itll be 72 100UMS 65 A* 58 A 51 B and who cares about the rest tbh... and i somehow couldnt get question 2, but i done everything else... btw what did you lot get for that completing the square integral that had a negative 1 as the coefficient of x^2 in the root

Did you get it in the form required? I remember it was something like pi + 6root3 - 6 or pi - 6root + 6.

2/3 arctan(x/2) or x/4, can't remember exactly
Maybe it was 4/3 arctan(x/4), one of the two.

there were limits so what was your answer in terms of pi?

72 for an A* is too high, people generally make mistakes, specially in FP3 so I think it will be 71/70.

Guys what would 60-64/75 be? thanks (:

Oh that's b then right? I can't remember but I think k was = 2.

he said 72 for 100UMS

Wasn't the answer for th pi / 3

A if you're lucky, but possibly a high B.

arcsin1-arcsin0.5 = pi/3 is what i got.

Solutions - Let me know if any need changing.
1)3 and -2
2)5/8+ln(3/2)
3)k=2
4)pi/3 2/3arctan(e^x/3)
5)25/3-32/15root2
6)9 then p=7 and q=5, the eigenvector is (2,1,-2) and then there will be varying orders of the eigenvectors for P.
7)1/12(pi+6root3-6)
8)7x+5y-9z=8 and my a was (11/8,-13/8,0) and b was (11/8,-1/8,1) although others may differ.
