Second Derivative

In this post, we understand the concept of the second derivative as the rate of change of the first derivative function, as a part of the QCE Maths Methods course under the topic Further Differentiation and Applications 3 and sub-part The Second Derivative and Applications of Differentiation.

Second Derivative

Part 1: Point of inflexion

Part 2: Turning point vs stationary point

Part 3: Point of inflexion might not exist when f''(x) = 0

Part 4: Examples where f''(x) = 0 doesn’t mean point of inflexion

Part 5: Concavity changes but f''(x) does not
