Corrections

Q4 answer is a2 (a squared) misread question thinking it said the smallest number.

Q12 Gradient between two points should’ve been written as y2-y1/x2-x1 not y1-y2/x2-x1

Answer is correct though

great video but why is the answer for q28, 9.5 when you said 55 metres?

[anup]

Sir, love your videos but for Q4 it should be a squared because the cubed would make it negative.
