haha nah you're pretty gangstuh!! haha.. not in a million years!! keep wishing.

pffftt you wish.

yup answer was 8

95+

same as you! but with silly mistakes, probably around 90-100. hopefully!!!

is there an easier way on learning- permutations, combinations, binomial theorem and induction? can't get my head around these topics.

just go through formulas or do past papers?

do you need a sum formula for q9?

I did that. What do U after to find centre and radius?

yup I think this is right. After integrating, you sub t=4 and get the volume

I got that too but my mates said the given equation was the rate at which the liquid is falling. So you needa integarte that to get the volume and sub t=4 after..

How do you do the locus question and the sum question at the end of q9

How do you do this question?

Focus on sor2u or maths ext.. Coming 7/11 in ext and fairly shit at it. Should I do past papers til Wednesday or just fcuk it and concentrate on sor? I got 11 units so in guessing ext maths won't count

there's no "end of question" if that question is written in one page.. Look at q 1-5.. All written in one page and has no end of question..

Although q 10 was fairly simple compared to other year.. I'd say that cut off will be around 94-98 because there were harder shit throughout the paper.. Not just the last questions.

good luck to everyone! and good luck to op, lol soz for stealing your thread

yeah cos you're finding the maximum velocity. which is dv/dt = 0 and dv/dt is acceleration. so in your question, solve for t when dv/dt = 0 and you have to prove that the value at t is a max by using first or second derivative test

when acceleration = 0

Lol yeah same here!!
