Question 7 and 8 are on the last page

Notify me of any errors, I'm not god I just did the paper again in 10 minutes so forgive me for minor mistakes

+ My computer handwriting is worse than my real handwriting

sorry about 3b) it should be g^-1(16) =2, not y=2

everything seems fine. i like how you put 42 on the end of question 2 haha

We didn't have to prove the last question was a maximum right?

I mean there was one r value and it asked for max so it's gotta be maximum.

I did in the actual exam, but no you would not. 1 for dS/dr = 0

and the other for the answer.

Extra stuff would be cm, proving maximum etc, but there is no need I think?

I used the fact that its a negative parabola to justify, but I doubt you'd need to for a 2 mark question

[Blakhitman]

I don't think it was required either.

especially since it was 2 marks.

It would be better to substitute that +c with a 0 or any other integer (or real number..) but I don't think you will be penalized.

I did the watchman method "therefore an antiderivative is...without the +c"

Awesome!
I was so tempted to add a "+1337" on the end, but I resisted
