## Introduction to Fourth Derivative Calculator:

The fourth derivative calculator is a digital tool that is designed to **compute the fourth derivative** of a function. Our tool can solve a variety of functions, including polynomial, trigonometric, exponential, and logarithmic for fourth derivation.

It is a useful tool for students, engineers, and scientists who need a reliable tool that can give them an accurate solution for the higher-order derivatives.

## What is the Fourth Derivative?

The fourth derivative of a function is defined as a process of finding the differentiation of the given **function four times**. It provides insights about the behavior and nature of the function. It is particularly useful in Taylor series expansions and the analysis of differential equations.

The 4th derivative calculator provides valuable information for understanding and modeling complex behaviors in various fields such as engineering, physics, and signal processing. It is denoted as,

$$ f^4 (x) \;=\; \frac{d}{dx} \left(\frac{d}{dx} \left(\frac{d}{dx} \left(\frac{d}{dx} f(x) \right) \right) \right) $$

## How to Find Fourth Derivative?

To find multivariable derivative function, you need to **differentiate** the function four times. Let's see the calculation process of the fourth derivative in steps.

**Step 1**: Identify the given function f(x), and choose the appropriate method for differentiation.

**Step 2**: Differentiate the function f(x) that you want to differentiate with respect to x as f`(x).

$$ f′(x) \;=\; \frac{d}{dx} (f(x)) $$

**Step 3**: Then again differentiate f′(x) to find the second derivative f′′(x).

$$ f′′(x) \;=\; \frac{d}{dx} f′(x) $$

**Step 4**: For third order derivation, differentiate f′′(x) with respect to x.

$$ f′′′(x) \;=\; \frac{d}{dx} (f′′(x)) $$

**Step 5**:Finally, differentiate f′′′(x) to find the fourth derivative f^{(4)}(x).

$$ f^(4)(x) \;=\; \frac{d}{dx} (f′′′(x)) $$

Each step involves applying the differentiation rules (product rule, chain rule, etc.) as per the original function behavior f(x).

If f(x) is given in a specific form (polynomial, trigonometric, exponential, etc.), then the fourth degree derivative calculator applies the differentiation rules accordingly.

## Practical Example Of Fourth Derivative:

The solved **example** of the fourth derivative function is given below to understand the calculation process of fourth derivative calculator.

**Example**:

$$ f(x) \;=\; cos (2x) $$

For fourth derivation, calculate the first, second, third, and fourth derivatives of f(x) = cos2(x).

**Solution**:

Use chain rule and differentiate the function f(x) with respect to x.

$$ f(x) \;=\; cos(2x) $$

$$ f’(x) \;=\; \frac{d}{dx} [cos(2x)] \;=\; -sin(2x) . \frac{d}{dx}[2x] \;=\; -2 sin(2x) $$

$$ f’(x) \;=\; -2 sin(2x) $$

Again take the derivative of f`(x) with respect to x.

$$ f’’(x) \;=\; \frac{d}{dx} [-2 sin(2x)] \;=\; -2 . \frac{d}{dx} [sin(2x)] \;=\; -2 . (2 cos(2x)) $$

$$ f’’(x) \;=\; -4 cos(2x) $$

Differentiate the function f```(x) with respect to x.

$$ f’’’(x) \;=\; \frac{d}{dx} [-4 cos(2x)] \;=\; -4 . \frac{d}{dx} [cos(2x)] \;=\; -4 . (-2 sin(2x)) $$

$$ f’’’(x) \;=\; 8 sin(2x) $$

To get the solution of the fourth derivative of a given function, differentiate the third derivative function f```(x) with respect to x.

$$ f^4 (x) \;=\; \frac{d}{dx} [8 sin (2x)] \;=\; 8 . \frac{d}{dx}[ sin(2x)] \;=\; 8 . (2 cos(2x)) $$

$$ f^4 (x) \;=\; 16 cos(2x) $$

Therefore the solution of f(x) = cos2(x) is given as,

$$ f^4(x) \;=\; 16 cos(2x) $$
