AQA C3 June 2014 Question 3

More differentiation ! Is there any different topics in this paper ?

This question is all about these topics, as in this question we are required to use all three types of our differentiation rules.

humm, on 3b. i think its '4x-3 / x^2 +1' . but i can still probably follow your method.

First part of the question, markscheme shows 5/2 x 2x(x^2+1)^3/2 ..That got me confused that they wouldn't accept my answer 5x(x^2 + 1)^3/2.

Lol you did 3b wrong, it asks to find the x coordinates and it's 4x-3
