42 A level Mathematics Paper 1 Edexcel 2018 Q2

This video walks through solving a calculus problem involving curve differentiation. We begin by finding the first derivative of a given curve equation and then proceed to calculate the second derivative. The problem then asks us to verify if the curve has a stationary point at x=4 by checking if the first derivative equals zero at that value. Finally, we determine the nature of this stationary point, specifically if it's a maximum or minimum, by evaluating the second derivative at x=4.
