I would say 74 for full. Making mistakes in the polar coordinates question was quite easy, not a lot of people will get 75/75

hmm i thought the polar was quite straight forward. I dont see what was tricky about it, other than it wasn't the usual 'find the exact value' style of q

For 4ii I integrated e^2x.sinx by parts and doing it twice I substituted e^2x.y but gut got a plus instead of a minus meaning I got y=1/3(cosx - 3sinx -e^2x) how many marks will I loose?

Drop 1 mark.

I had a sign error and for the 53/480 question I got 153/480. How many marks do you think i lost?

My working for the polar integral was incomplete as i ran out of time. How mant marks do you think I'd get for evaluating the integral of curve 2 between 0 and arccos (3/4)?

Hi @Zacken , cheers for taking the time to post this mate! Know you must get about 1000 questions a day but if you could, bear with me. All of my answers bar the second part of Q4 (which I left as ye^2(theta) = integral of {e^2(theta)sin(theta)} then did IBP once) matched yours

How important is your working to gain marks? Some of my workings were different to yours and I skipped some steps due to time pressure, would this significantly affect my grade?

How many marks would I lose for Q4b)?

I forgot how to do the de moivre's theorem question so for the next part integrating I did it interms of A B and C. How many marks would you say this would be if any?

Thanks Zacken. So at an estimate, I have 67. I was meant to go back to draw in the complex numbers but ran out of time -_-.

Could scrape an A* if you're very lucky.

Cheers mate, well done!



Shouldn't affect your grade at all unless your skips were massive.



Probably drop 4 marks.
.

M2 will be my saving grace . It's about the 270, not the 90. As long as I definitely have an A in Fp2, I should be fine.

Thank you for the solutions . It's very noble/kind of you to take the time to make them.

@zacken for the last question working out was correct but part of my second integral my limits where wrong and therefore answer was wrong how many marks lost?

I think 73 for full, particularly since the first order diff eqn seemed to have tripped up many people. The rest of it seemed doable, with part Bs having a 'show that' question which confirms your answer to part A. Thoughts?

I was an idiot and decided that $(z^n - z^{-n}) = -2i\sin \theta$ All the minuses cancelled out in the end, how many marks do you think I would have lost?
