A-Level Maths Question Differentiation helpWatch
You should not use a calculator during this question btw.
I've now got y=((2/e^2)+ 1)x - ((e/e^2 )+1 ) + ln3
its close but somehow need to add the 1 in the brackets to the 2/e^2 bit ? so that it looks the same as what im trying to prove
(this is the bit I was confused about at the start when I first got the gradient as its not the same )?
