question 8b, I didn't use the first part of the question and I just did the second part as is and i got something like sin3y - 3ycos3y = -1/9(4+9x) + 1/36 + pi
second of all all it said waas find dy/dx didnt specifiy simplified form so yous hould get it
Im not sure tbh, i did quotient rule on both x and y and ended up with a 4 tier fraction. Then i subbed t into each line separately and got that answer.
AQA scan and send our papers to multiple examiners to mark right, and the marks we get is the average of that?, or is it just 1 guy who marks it all
One examiner marks your paper, but a few papers are sent to two examiners at random to judge how accurately they're marking, if they're marked by two maybe they take the average. I think that's how my teacher said it works, anyway
