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.

For the volume one I got 512-1024/5 not 544-1024/5, I know what I got wrong but how many marks would I get? (Also how many marks was the question)

Lose 2.

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?

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?

No, it was over 5, and the numerator was close to 1696, it might have been 1696, but I remember 1637 or something like that, but I know 1696 is right.
