Derivative Video transcript. - [Voiceover] So what I want to do in this video is familiarize ourselves with the second derivative test and before I even get into the nitty-gritty of it, I really just want to get an intuitive feel for what the second derivative test is telling us. So let me just draw some axes here.

Derivative The Second derivative test exercise appears under the Differential calculus Math Mission. This exercise practices the second derivative test as a justification for the type of extreme value in a graph. There is one type of problem in this exercise: Use the second derivative to determine the extreme value: This problem provides a function and possibly a critical point. The user is expected to

### What is the second derivative??

The second derivative is the rate of change of the rate of change of a point at a graph (the "slope of the slope" if you will). This can be used to find the acceleration of an object (velocity is given by first derivative). You will later learn about concavity probably and the Second Derivative Test which makes use of the second derivative.

### How to use the second derivative test to identify relative maximum??

It explains how to use the second derivative test to identify the presence of a relative maximum or a relative minimum at a critical point. If the second derivative is positive at a critical number - a local minimum is present. If the second derivative is negative at a critical number - a local maximum is present.

### What is a derivative calculator and how to use it??

Moreover, an Online Derivative Calculator helps to find the derivation of the function with respect to a given variable and shows complete differentiation.

### Is x=0 an inflection point in the second derivative test??

Now, the second derivate test only applies if the derivative is 0. This means, the second derivative test applies only for x=0. At that point, the second derivative is 0, meaning that the test is inconclusive. So you fall back onto your first derivative. It is positive before, and positive after x=0. Therefore, x=0 is an inflection point.
