## How Does the Fourth Derivative Calculator Work?

The fourth derivative calculator works by finding the fourth-order derivative of the given function. The value of ‘n’ in the calculator shows the required order of the derivative.

This value should be equal to four to calculate the fourth-order derivative. This calculator is useful when there is knowledge about the derivative and its importance in calculus.

### What Is the Derivative?

The derivative is the rate of change of one quantity with respect to another. The procedure of determining the derivative of a function is called differentiation.

The derivative of a function ‘f(x)’ is denoted by ‘d/dx (f(x))’. The meaning of the derivative in calculus can be understood by considering the curve of a function ‘f(x)’ and then taking two points on it. One is ‘(x, f(x))’ and the other is ((x+h), f(x+h)).’

Afterward, draw the secant line on this curve that passes through these two points. When the distance between the two points is approximately zero, the second point co-joins the first point,t, and eventually, the secant line becomes the tangent line.

The slope of this tangent line is considered the derivative of a function in calculus. It is defined mathematically as:

d/dx (f(x)) = slope of the tangent = $\lim_{h\to 0} \frac{f(x+h) – f(x)}{h}$

The above-limit formula is used to calculate the derivative of a function, and it is called finding the derivative by using the first principle.

The derivatives are applied to optimize the functions. The intervals where the function is either increasing or decreasing are also found by using the derivatives. They are used to determine a quantity’s velocity by calculating the displacement derivative.

### Higher Order Derivatives

The higher order derivatives, such as the fourth derivative, are determined by finding the successive derivatives of a given function. For instance, when it is required to find the second order derivative, first find the first derivative and then take the derivative of the first derivate.

Similarly, the fourth-order derivative can be calculated by taking the first, second, third, and fourth derivatives one after the other. The fourth derivative is denoted by $d^4y/dx^4$.

### Primary Rules of the Derivatives

Some primary rules are used while finding the derivatives. These rules are explained below.

#### Power Rule

The power rule states that the derivative of a function with an exponent is equal to that exponent multiplied by the function with one decreased power.

#### Sum and Difference Rule

This rule defines the distributive property of the differentiation process. The process can be distributed over summation and subtraction.

#### Product Rule

When finding the derivative of a function that is the product of the two functions, then the product rule states the derivative of that function in the following way.

The derivative is equal to the summation of the first function multiplied by the derivative of the second function and the second function multiplied by the derivative of the first function.

#### Constant Rule

The derivative of the constant is equal to zero according to the constant rule of the derivative.

## Solved Examples

For a better understanding of how the calculator works, let’s have a look at some solved examples.

### Example 1

A physics student is asked to find the jounce for a given position vector in the exam. For this, he needs to calculate the fourth-order derivative of the following function.

$f(x) = 3x^{5} + 2x^{3} -\, 6x + 4$

### Solution

This problem can be easily solved using the Fourth Derivative Calculator. The answer is given as follows:

$\frac{d^4}{dx^4} (3x^{5} + 2x^{3} -\, 6x + 4) = 360x$

### Example 2

While solving a vision problem, a machine learning researcher encounters a function. To further solve the problem, it is required to find out the fourth-order derivative of the function.

$f(x) = x^{2} sin(x)$

### Solution

The fourth order derivative for the above function is given below:

$\frac{d^4}{dx^4} (x^{2} sin(x)) = (x^{2} – 12) sin(x)\, -\, 8x cos(x)$
