    for 8a if you write it in vector form u lose the mark because they asked for coordinates
    Not true, they gave the 'coordinates' of P in column vector form

    swear the 8c is 2 rt 2 not 2?
    the modulus was 2rt2 yes

    But it said in the question it is "krt2" so k has just been given as 2

    yeah it was 2 root 2 . The question said exoress in the form k root 2 , so that just means the k bit was 2

    Y = (2x-1)^(3/4) I believe?
    I'm thinking I had the fraction as 1/10 rather than 1/5, but that would give me an answer that was way off, and I seem to be closer to the answer. Hopefully I'm just forgetting what I wrote and got it right.

    Anyone know how many marks I'd lose if I accidentally did the cos(piy) and differentiated correctly but I forgot it was y and differentiated like it was X, so didn't do it implicitly. This made my dy/dx wrong and hence the next bit of the question wrong?

    Lose 2.
    Thanks, also for the last one I got area as 3.2 cause I did 1/2absinc using 2root2 =a=b and Accidental used angle as 0.8 from part above
    Instead of 0.6, any marks out of 2? Or lost those 2 as well?
