Introduction to the derivative of x^2/3

Derivatives have a wide range of applications in almost every field of engineering and science. The x^2/3 derivative can be calculated by following the rules of differentiation. Or, we can directly find the derivative formula of x^2/3 by applying the first principle of differentiation. In this article, you will learn what the x derivative formula is and how to calculate the derivatives of x^2/3 by using different approaches.

What is the derivative of x^2/3?

The derivative of (x)^2/3 with respect to the variable x is equal to 2/3x^(-⅓). It measures the rate of change of the algebraic function x^2/3. It is denoted by d/dx(x^2/3) 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 x^2/3 formula

The formula for derivative of f(x)=x^2/3 is equal to the 2/3x^(-⅓), that is;

$f'(x) = \frac{d}{dx}(\frac{x^2}{3}) = \frac{2}{3}x^{-⅓}$

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

d/dx (x^n)=nx^n-1

How do you differentiate x^2/3?

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

1. Power rule
2. Product Rule
3. Quotient Rule

Each derivative rule provides a different way to compute the x^2/3 differentiation. By using these methods, we can mathematically prove the formula for finding the differential of x^2/3.

Derivative of x^2/3 by power rule

The formula for derivative x^⅔ can be calculated by using the power rule because it is used to calculate derivatives of algebraic functions with some power. The power rule derivative is defined as;

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

Proof of x^2/3 derivative formula by power rule

To differentiate x^2/3 by using power rule, we start by assuming that,

$f(x)=x^{⅔}$

Differentiating both sides with respect to x.

$f’(x)=\frac{d}{dx}(x^{⅔})$

Now by applying the power rule formula of derivatives.

$f’(x)=\frac{2}{3}.(x^{⅔ -1})$

$f’(x)=\frac{2}{3}(x^{\frac{2-3}{3}})$

Simplifying, 

$f’(x)=\frac{2}{3}(x^{-⅓}){2}nbsp;

Hence we have verified the derivative of x^⅔ by using the power rule formula. Also, this formula is also applicable to calculate the differentiation of x squared.

Derivative of x^2/3 by product rule

The formula for derivative x^2/3 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^2/3 by product rule

To differentiate of x^2/3 by using product rule, we start by assuming that,

$f(x) = 1.x^{⅔}$

By using product rule of differentiation,

$f’(x) = (0). x^{⅔} + \frac{2}{3}(x^{-⅓})$

We get,

$f’(x) = 0 + \frac{2}{3}(x^{-⅓})$

Hence,

$f’(x) = \frac{2}{3}(x^{-⅓})$

Derivative of x to the power 2/3 using quotient rule

Another method for finding the differential of x^2/3 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:

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

Proof of differentiating x by quotient rule

To prove the x^2/3 derivative, we can start by writing it,

$f(x) = \frac{x^{⅔}}{1} = \frac{u}{v}$

Supposing that u = x^2/3 and v = 1. Now by quotient rule,

$f’(x) = \frac{vu’ - uv’}{v^2}$

$f’(x) = \frac{1\frac{d}{dx}(x^{⅔}) - x^{⅔}. \frac{d}{dx}(1)}{1^2}$

$f’(x)= \frac{\frac{2}{3}(x^{-⅓}) - x^2/3(0)}{1}$

$f’(x)= \frac{2}{3}(x^{-⅓})$

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