## Introduction to the derivative of x^4

Derivatives have a wide range of applications in almost every field of engineering and science. The x^4 derivative can be calculated by following the rules of differentiation. Or, we can directly find the derivative formula of x^4 by applying the first principle of differentiation. In this article, you will learn what the x^4 derivative formula is and how to calculate the derivatives of x^4 by using different approaches.

## What is the derivative of x^4?

**The derivative of (x)^4 with respect to the variable x is equal to 4x^3. It measures the rate of change of the algebraic function x^4. It is denoted by d/dx(x^4) which is a fundamental concept in calculus.**

Knowing the formula for derivatives and understanding how to use it can be used in solving problems related to velocity, acceleration, and optimization.

## Derivative of x4 formula

The formula for derivative of f(x)=x^4 is equal to the 4x^3, that is;

$f'(x) = \frac{d}{dx} (x^4) = 4x^3$

It is calculated by using the power rule of differentiation, which is defined as:

$\frac{d}{dx}(x^n)=nx^{n-1}$

## How do you differentiate x^4?

There are multiple ways to prove the differentiation of x4. These are;

- First Principle
- Product Rule
- Quotient Rule

Each method provides a different way to compute the x^4 differentiation. By using these methods, we can mathematically prove the formula for finding the differential of x^4.

## Derivative of x^4 by first principle

According to the first principle of derivative, the x^4 derivative is equal to 4x^3. The derivative of a function by first principle refers to finding a general expression for the slope of a curve by using algebra. It is also known as the delta method. The derivative is a measure of the instantaneous rate of change, which is equal to,

f(x) = lim f(x + h) - f(x) / h

This formula allows us to determine the rate of change of a function at a specific point by using the limit definition of derivative.

### Proof of x^4 derivative formula by first principle

To prove the derivative of x4 by using first principle, replace f(x) by x^4 or you can replace it by x^2 to find the derivative of x^2.

$f(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

$f'(x) = \lim_{h \to 0} \frac{(x + h)^4 - x^4}{h}$

Moreover,

$f'(x) = \lim_{h \to 0} \frac{x^2 + 4x^3h + 6x^2h^2 + 4xh^3 + h^4 - x^4}{h}$

$f'(x) = \lim_{h \to 0} \frac{4x^3h + 6x^2h^2 + 4xh^3 + h^4}{h}$

When h approaches to zero,

$f’(x)=4x^3$

Hence the differentiation of x^4 is equal to 4x^3. Also calculate the differentiation of x4 graph by using our derivative grapher.

## Derivative of x^4 by product rule

The formula for derivative x^2 can be calculated by using the product rule because an algebraic function can be written as the combination of two functions. The product rule derivative is defined as;

$[uv]’ = u’.v + u.v’$

### Proof of differentiating of x^4 by product rule

To differentiate of x^4 by using product rule, we start by assuming that,

$f(x) = x^2. x^2$

By using product rule of differentiation,

$f’(x) = (2x). x^2 + (x^2)(2x)$

We get,

$f’(x) = 2x^3 + 2x^3$

Hence,

$f’(x) = 4x^3$

## Differentiation of x4 using quotient rule

Another method for finding the differentiation of x4 is using the quotient rule, which is a formula for finding the derivative of a quotient of two functions. Since the secant function is the reciprocal of cosine, the derivative of cosecant can also be calculated using the quotient rule. The derivative quotient rule is defined as:

$\frac{d}{dx}\left(\frac{f}{g}\right) = \frac{f’(x). g(x) - g’(x).f(x)}{(g(x))^2}$

### Proof of x^4 derivative by quotient rule

To prove the x^4 derivative, we can start by writing it,

$f(x) = \frac{x^4}{1}= \frac{u}{v}$

Supposing that u = x^4 and v = 1. Now by quotient rule,

$f’(x) = \frac{vu’ - uv’}{v^2}$

$f’(x) = \frac{1.(x^4) - x^4.(1)’}{(1)^2}$

$f’(x)= \frac{4x^3}{1}$

$f’(x)=4x^3$

Hence, we have derived the derivative of x^4 using the quotient rule of differentiation. Use our quotient rule calculator with steps to find the derivative of any quotient function.
