it was 1 to infinity


Thank you so much - so many were talking about 1/x being a reason for improper Integral I started to worry😁
Just looked at it- what is funny is most of the paper is pretty much the same topic 2019 compared to 2020😳 now there is a hint!

Can you share the 2019 paper with me please
Paper 2 was harder I thought last year
So is everyone a resit student with poor CAG grades or just private candidates?

I think I had B as 13 but A is -8

I think I got the same as you. Defo had A = -8 but can't remember B

Poor CAGs. Lol didn't get into my 1st or 2nd choice
Q1) 4/3
Q2)1/5 x ln(7/2) confirmed with improper integral calculator
Q3) 9root3 -4π
Q4a) 4x + y + 2z =10
b) something over 25 for all of them
c) 41°
5) A=-8 B=1
6) proof
7a) 10277 or something like that
Rate of change after 4 hrs = 1.0something

Should the rate of change not be 1000 something, as the variable was in thousands? (for number 7)

**** I must’ve Overlooked that but yeah I think you’re right
Actually wouldn’t it be 1.0something because it’s P(h^-1) and the P represents thousands?

idk bruh, can't change my answer so no real point thinking about it.

Actually, I think dP/dt = 1.0something but for the rate of change of the bacteria I think 1000 something

Any one have this book

i think they asked for the rate of change of bacteria though, so it would be 1000 smth
I couldnt get 6B because it doesnt bloody work for all N. Try N = 2 . 16 25 36 = 77!!!!!!!

It said positive odd integers not positive integers

I only realised that when I went back to that question at the end then ran out of time
