Thank you. How many marks would I lose for forgetting to work out c on 4ia? I also made a slip in subtraction, using a different method to you, at the very end of 4ii which meant all my answers where wrong by a factor of -1, I'm hoping just 1 mark (I was so happy with my method too).
Otherwise, I'm confident with getting the marks for every other question aslong as the examiner checks the last page I wrote on for my second attempt at polar coordinates. Also, would the examiner allow me to use A for the angle at which they intersect rather than 0.72 whatever, I did state A = 0.72..
