A second-order differentiation calculator is an online tool for finding the derivative of the functions online. This second derivative test calculator tool provides its users with free services without any subscription charges.

This tool gives you meaningful answers in no time. The double differentiation calculator is easy to use and has a user-friendly interface.

## What is the Double Derivative Calculator?

The second derivative calculator with steps is online to get the second-order derivative of the given function. The second-order derivative means that the function is differentiated two times instead of evaluating a single derivative.

This is called a second-order derivative. This 2nd derivative calculator is for the evaluation of such kinds of differentiation. The second-order differentiation calculator is easy to handle. The 2nd order derivative calculator gives accurate and reliable results in a fraction of a second.

The second order derivative calculator helps students, beginners, and others away from long and hectic calculations.

## Formula Used by 2nd Derivative Calculator

A double differentiation calculator is an online tool that works on the following given formula for the process of differentiation.

$$P(x) \frac{d^2y}{dx^2} + Q(x) \frac{dy}{dx} + R(x) y \;=\; 0$$

Let's see how to use this formula for the calculation of second derivative of a function.

Example: Find second derivative for the function tan-1x, with respect to "x".

Solution : Let's take a y = tan-1x

Differentiate w.r.t "x"

$$\frac{dy}{dx} \;=\; \frac{d}{dx} tan^{-1}x$$ $$\frac{dy}{dx} \;=\; \frac{1}{1+x^2}$$

Again differentiate w.r.t "x"

$$\frac{d}{dx} \left( \frac{dy}{dx} \right) \;=\; \frac{d}{dx}\left( \frac{1}{1+x^2} \right)$$

## How does Second Derivative Test Calculator Work?

The user interface of the 2nd derivative is very easy. By following the simple given steps one can get the solution to his/her problems. The double derivative calculator usually follows the following steps to calculate the second-order derivative of the given function:

• First of all, Enter the function in the required input field.
• Select the variable w.r.t to which you want to differentiate.
• Now click on the "CALCULATE" button to get the second-order derivative.

Finally, the derivative of the function's derivative will display on the screen. Not it only contain the double derivative, but also it has possible intermediate steps, plots and trigonometric form of given function.
