    No. 2 and 2+/-root2
    Yeah, getting them in surds put me off and I wasted my time checking it thrice because I thought they wouldn't do that for some reason... At least I got the surds though.

    Literally the worst exam experience ever lol, i cant believe i flopped the paper so badly for some reason i also got 1,2,3 as the eigenvalues and couldnt even do the stupid last question and messed up on part b for the reduction formulae so maybe only got maximum 52 ish marks, hopefully I will get at least a B for this paper but thats not too bad I just need an A overall for Further Maths.
    If it helps I got 1,2,3 too ((((((((((

    The answers for eigen values were definately 2,2+-root2

    Did you guys apply the + - + rule?
    That's nothing to do with M=PDP(-1) that's to do with cofactors and finding inverse matrices

    You only had to find P such that it was orthogonal, but they made you find the normalised eigenvectors before anyway!

    I should not 😂. I will not after my disasterous factorisation in FP2 haha.

    It wasn't 1-sqrt(2) since sinh(x) = 1/2 only has one solution at x=ln(1+sqrt(2))

    Wow that was tough! Do you reckon it was as hard as last years? If so, do you reckon grade boundaries will be similar? It was 62 for an A* last year...

    Wasn't it just 1+root2 because 1-root2 < 0?

    does FP3 have to count towards the A*? I also did FP2, M2, S2 this year so can I get the A* with those three or does there have to be a level3 module (eg FP3/M3) in there?
