    Only just started AQA c3 and covered chain, product and quotient rule but I have no idea how to do the last integral question on my homework sheet (unfortunately due in tomorrow).
    Any help appreciated, thanks. Name:  image.jpg

    May be a bit late now. But if you differentiate the first one you should get (3/2)x^2(x^3+2)^-1-2
    So if we integrate x^2(x^3+2)^-1/2 it is just 2/3 of the expression we differentiated in the previous question so the answer will be 2/3 (x^3+2)^1/2 +c. Try not to forget the constant of integration as sometimes you will be penalised for it.
