Those ones are easier done without the quotient rule. :)
Yeah haha, I usually just blindly dive into quotient rule and hope for the best :p

Haha. Quotient rule is something nice to avoid if possible as it is a bit tedious. :)

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread

I differentiated the equation in part a then sub in 1 for x , so y'Capture.PNG= 2a-2ax , then when you sub in 1, you get y=2a-2a

Can someone tell me where I went wrong, because the answ2r is 2a-a^2
