Even if i used subsitution i would not be able to do the question because of the fact that i do not know how to integrate a constant raised to a power because its not in any book or in the spec so my teachers didnt bother teaching it
I wasn't taught it either, I've emailed edexcel to ask about it as it isn't it any textbook
if you had looked at the jan 13 paper you would have learnt how to do it. Just shows you didn't revise enough tbh
Considering I taught myself the subject I shouldn't have to do every single past paper to uncover that. It's simple, if edexcel are going to ask a question on something it should be included in the textbook

Well that's your own fault for not doing enough papers.
