How to calculate points of inflection
WebInflection points are stationary points but they are not turning points. How to Find Stationary Points To find stationary points: Differentiate the function. Set this derivative … WebFind the stationary points on the curve y = x 3 - 27x and determine the nature of the points: At stationary points, dy/dx = 0 dy/dx = 3x 2 - 27 If this is equal to zero, 3x 2 - 27 = 0 Hence x 2 - 9 = 0 (dividing by 3) So (x + 3) (x - 3) = 0 So x = 3 or -3 d 2 y/dx 2 = 6x When x = 3, d 2 y/dx 2 = 18, which is positive.

Web30 jul. 2014 · 1 Answer. If y = f (x) is the cubic, and if you know how to take the derivative f '(x), do it again to get f ''(x) and solve f ''(x) = 0 for x; the inflection point of the curve is at (x,f (x)). The 2nd derivative measures the concavity, down or up, and the inflection point is where that changes from negative to positive, so f is equal to 0 there.
