Nature of a stationary point using the first differential
In this tutorial I show you how to distinguish whether a stationary point is a maximum, minimum or point of inflexion by considering the first differential.
Nature of a stationary point using the second differential
In this tutorial I show you how to distinguish whether a stationary point is a maximum, minimum or point of inflexion by considering the second differential.
Example
In this next example I put together all the ideas discussed so far.
