Introduction

Implicit differentiation is a powerful tool in calculus that allows us to find the derivative of an implicitly defined function. In this article, we will explore the process of implicit differentiation and compare it to explicit differentiation. We will use the equation $5x^4 + y^3 = 6x$ as a case study to demonstrate the application of implicit differentiation and explicit differentiation.

Implicit Differentiation

Implicit differentiation is a method of finding the derivative of an implicitly defined function. The process involves differentiating both sides of the equation with respect to the independent variable, while treating the dependent variable as a function of the independent variable.

Step 1: Differentiate Both Sides of the Equation

To find the derivative of the equation $5x^4 + y^3 = 6x$, we will differentiate both sides of the equation with respect to $x$. We will use the chain rule to differentiate the term $y^3$.

$$\frac{d}{dx}(5x^4 + y^3) = \frac{d}{dx}(6x)$$

Using the power rule and the chain rule, we get:

$$20x^3 + 3y^2 \frac{dy}{dx} = 6$$

Step 2: Solve for $\frac{dy}{dx}$

To find the derivative of the equation, we need to solve for $\frac{dy}{dx}$. We can do this by isolating the term $\frac{dy}{dx}$ on one side of the equation.

$$3y^2 \frac{dy}{dx} = 6 - 20x^3$$

Dividing both sides of the equation by $3y^2$, we get:

$$\frac{dy}{dx} = \frac{6 - 20x^3}{3y^2}$$

Conclusion

In this section, we used implicit differentiation to find the derivative of the equation $5x^4 + y^3 = 6x$. We differentiated both sides of the equation with respect to $x$ and solved for $\frac{dy}{dx}$.

Explicit Differentiation

Explicit differentiation is a method of finding the derivative of an explicitly defined function. The process involves differentiating the function with respect to the independent variable.

Step 1: Differentiate the Function

To find the derivative of the function $y = \sqrt[3]{\frac{6x}{5x^4}}$, we will use the chain rule and the power rule.

$$y = \sqrt[3]{\frac{6x}{5x^4}}$$

Using the chain rule and the power rule, we get:

$$y' = \frac{1}{3} \left(\frac{6x}{5x^4}\right)^{-\frac{2}{3}} \left(\frac{6}{5x^4} - \frac{24x^3}{5x^4}\right)$$

Simplifying the expression, we get:

$$y' = \frac{1}{3} \left(\frac{5x^4}{6x}\right)^{\frac{2}{3}} \left(\frac{6 - 24x^3}{5x^4}\right)$$

Step 2: Simplify the Expression

To simplify the expression, we can cancel out common factors.

$$y' = \frac{1}{3} \left(\frac{5x^4}{6x}\right)^{\frac{2}{3}} \left(\frac{6 - 24x^3}{5x^4}\right)$$

Canceling out the common factor of $5x^4$, we get:

$$y' = \frac{1}{3} \left(\frac{5}{6x}\right)^{\frac{2}{3}} \left(\frac{6 - 24x^3}{x^4}\right)$$

Conclusion

In this section, we used explicit differentiation to find the derivative of the function $y = \sqrt[3]{\frac{6x}{5x^4}}$. We differentiated the function with respect to $x$ and simplified the expression.

Comparison of Implicit and Explicit Differentiation

Implicit differentiation and explicit differentiation are two different methods of finding the derivative of a function. Implicit differentiation is used when the function is implicitly defined, while explicit differentiation is used when the function is explicitly defined.

Advantages of Implicit Differentiation

Implicit differentiation has several advantages over explicit differentiation. One of the main advantages is that it can be used to find the derivative of an implicitly defined function, even if the function is not explicitly defined.

Another advantage of implicit differentiation is that it can be used to find the derivative of a function that is defined in terms of another variable. For example, if we have a function $y = f(x)$ and we want to find the derivative of $y$ with respect to $x$, we can use implicit differentiation to find the derivative of $y$ in terms of $x$.

Disadvantages of Implicit Differentiation

Implicit differentiation also has several disadvantages. One of the main disadvantages is that it can be more difficult to use than explicit differentiation. This is because implicit differentiation requires us to differentiate both sides of the equation with respect to the independent variable, which can be a complex process.

Another disadvantage of implicit differentiation is that it can be more prone to errors than explicit differentiation. This is because implicit differentiation requires us to solve for the derivative of the function, which can be a difficult process.

Conclusion

In this article, we compared implicit differentiation and explicit differentiation. We used the equation $5x^4 + y^3 = 6x$ as a case study to demonstrate the application of implicit differentiation and explicit differentiation. We found that implicit differentiation has several advantages over explicit differentiation, including the ability to find the derivative of an implicitly defined function and the ability to find the derivative of a function that is defined in terms of another variable. However, we also found that implicit differentiation has several disadvantages, including the difficulty of use and the potential for errors.
