Great slides, thank you. I have a comment on concave/convex. I feel that these are the wrong way round on slide 37. Although you can say that a concave down is the same as concave up, I believe that just saying 'concave' means the 2nd derivative is negative. The illustatration has them the other way around. Any other thoughts on this?

Slide 46, should read "answer must either be ð’™=ðŸ-ðŸ/√ðŸ‘". 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 13 Q 5 looks like exponent incorrect. Thanks Jamie - VVP

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.

How do we tell what type of stationary point? visual display slide. The "gradient just after" for "maximum point" says positive but should be negative
