Why second-order derivative is used?

And the second derivative is used to define the nature of the given function. For example, we use the second derivative test to determine the maximum, minimum or the point of inflexion.

How is second-order derivative written?

In functional notation, the second derivative is denoted by f″(x). In Leibniz notation, letting y=f(x), the second derivative is denoted by d2ydx2.

What is the second-order derivative operator?

Ans : The laplacian is a derivative operator of the second order.

What is second-order derivative test?

The second derivative test is a systematic method of finding the absolute maximum and absolute minimum value of a real-valued function defined on a closed or bounded interval. Here we consider a function f(x) defined on a closed interval I, and a point x= k belongs to a closed interval (I).
