## Introduction to Second Derivative Calculator:

Second derivative calculator is an online source that is used to **find the second derivative** of a given function with its differential variable. Our tool analyze the behavior of a function's concavity and determine points of inflection.

This double derivative calculator is a handy tool for everyone who want to quickly analyze the behavior of functions to determine the concave up or concave down, or points of inflection on a graph.

## What is the Second Derivative?

Second derivative of a function is the rate of change of the **rate of change of a function** that varies with respect to its variable. This method is used to measure the slope of the tangent line (which is the first derivative) changes as you move along the graph of the function.

The first derivative, f′(x), represents the rate of change of f(x). The second derivative, f′′(x), represents the rate of change of f′(x), or equivalently, the curvature of the graph of f(x). It is used in calculus and physics for analyzing motion, rates of change, and curvature.

## How to Calculate Second Derivative?

To **calculate the second derivative** of a function, the 2nd derivative calculator follows some rules of differentiation. Here is a step-by-step process to find the second derivative f′′(x) of a function f(x).

**Step 1**:

Start with the original function f(x) whose second derivative you want to find.

**Step 2**:

Compute the first derivative f′(x), and use the power rule or any other differentiation rules that are helpful.**Step 3**:

Compute the second derivative f′′(x), when you have f′(x), differentiate it again to find f′′(x).

By following these steps and rules, you can systematically find the second derivative of given functions in calculus.

## Solved Example of Second Derivative:

The solved **example** of the second derivative function will help you understand the calculation process of our second derivative calculator.

**Example**:

$$ f(x) \;=\; x^3 - 3x $$

**Solution**:

Take the first derivative with respect to x,

$$ f’(x) \;=\; 3x^2 - 3 $$

Take the second derivative with respect to x,

$$ f’’(x) \;=\; 6x $$
