Slide 46, should read "answer must either be 𝒙=𝟏-𝟏/√𝟑". Many thanks for the resources.

(Picking up on Mr. V Van Pelt comment, 5 Dec): Slide 13, example 5 looks to be incorrect. f'(x) = 49/2 x-to-the 5/2

slide 16, 8(1/2) -8 should it not be -4 instead of 4 as 8*1/2 = 4, and 4 - 8= -4

Slide 4, I can't see anywhere squared of -3. The calculations are for the gradient.
