Product Rule Calculator with Steps

Product rule derivative calculator is a useful tool for students, teacher, professional or researcher who wants to find the product rule derivation function solution.

What is the Product Rule?

Product rule is the process in calculus, used to find the derivation of product of two or more than two functions. For example, the first function is f(x) and the second function is g(x). The product rule of f(x) . g(x) formula used by the derivative calculator product rule is,

$$ (f(x) . g(x))’ \;=\; f’(x) . g(x) + f(x) . g’(x) $$

The product rule function is f(x) . g(x) and its differentiation is (f(x) . g(x))`. This rule is essential in different fields such as mathematics, economics, physics and engineering etc.

How to Find Derivative Product Rule?

The product rule is a systematic method to find the derivative function that cannot be solved with direct differential rule. Here’s a step-by-step guide on how to apply the product rule:

Step 1:

Identify the two functions that is being multiplied. Suppose you have a product of functions f(x) and g(x).

$$ h(x) \;=\; f(x) ⋅ g(x) $$

Step 2:

Differentiate each function f(x) and g(x) with respect to x separately. Find f′(x), the derivative of f(x) and g′(x), the derivative of g(x).

Step 3:

Use the product rule formula and add the value of f`(x) and g`(x),

$$ (f(x) . g(x))’ \;=\; f’(x) . g(x) + f(x) . g’(x) $$

Step 4:

Simplify the expression after adding the value of f(x) and g(x) and its derivation value respectively.

Step 5:

After simplification, you get the solution of your given product rule derivation function.

By following these steps, you can easily apply the product rule to find the derivative of the product of functions.

Practical Example of Product Rule:

The example of product rule derivation problem will help you in the conceptual clarity of calculation process of product rule calculator with steps.

Example: Differentiate the following:

$$ y \;=\; x^{-2} (4 + 3x^{-3}) $$

Solution:

Differentiate with respect to x,

$$ y’ \;=\; x^{-2} D[4 + 3x^{-3}] + D[x^{-2}] (4 + 3x^{-3}) $$

$$ =\; x^{-2} (-9x^{-4}) + (-2x^{-3})(4 + 3x^{-3}) $$

$$ =\; -9x^{-6} - 8x^{-3} - 6x^{-6} $$

$$ =\; -15x^{-6} - 8x^{-3} $$

$$ =\; \frac{-15}{x^6} - \frac{8}{x^3} $$

$$ =\; \frac{-15}{x^6} - \frac{8x^3}{x^6} $$

$$ =\; -\frac{15 + 8x^3}{x^6} $$

What is the difference between chain rule and product rule

The chain rule and the product rule are both important rules in calculus for finding the derivatives of functions, but they are used in different situations. Here's a detail about how they differ:

Chain Rule:

The chain rule is used to differentiate composite functions. It helps you find the derivative of a function that is composed of two or more functions. To determine chain rule, following formula is used:

$$ \frac{d}{dx} [f(g(x))] \;=\; f’ (g(x)) . g’(x) $$

Product Rule:

The product rule is used to differentiate the product of two functions. It helps you find the derivative of a function that is the product of two other functions. Mathematical Statement is:

$$ \frac{d}{dx} [u(x) . v(x)] \;=\; u’(x) . v(x) + u(x) . v’(x) $$

You differentiate the first function and multiply by the second function, then add the product of the first function and the derivative of the second function.

When to use product rule vs chain rule

The product rule and chain rule are both used for finding the derivatives of functions, but they are used in different ways. Here’s a detail on when and how to use each rule.

Use the product rule when you need to find the derivative of a function that is the product of two or more functions.

If you have h(x)=u(x).v(x)

$$ h`(x) \;=\; u`(x) . v(x) + v`(x) . u(x) $$

If you have a function where two separate functions are multiplied, then you can apply the product rule.

Use the chain rule when you need to find the derivative of a composite function that one function is inside another function.

If h(x) = f(g(x)) h(x) then,

$$ h′(x) \;=\; f′(g(x)) ⋅ g′(x) $$

When you have a function composed of another function, then you can apply the chain rule.

Does derivative product rule work for negative exponents

Yes, the product rule for derivatives works for functions with negative exponents, as it does for functions with positive exponents. The presence of negative exponents does not change the fundamental rules of the product rule. However, it may require some algebraic expression and simplification for these types of given expressions.

Why not use the product rule for derivative of 5sinx

The product rule is not used for 5sin⁡(x) because this function is a constant times a single function, and the constant multiplication rule is more straightforward than any other method. The product rule is applied only when you have the product of two different functions.

How to calculate a triple product rule

To the calculation of the triple product rule, let's take an example of the triple product rule with a solution to know its working process.

Example:

Find the derivative of f(x) = (x^2 + 1) . sin(x) . e^x

Solution:

Apply triple product rule formula,

$$ \frac{d}{dx} [u(x) . v(x) . ω(x)] \;=\; u’(x) . v(x) . ω(x) + u(x) . v’(x) . ω(x) + u(x) . v(x) . ω’(x) $$

Differentiation with respect to x,

$$ u(x) \;=\; x^2 + 1,\; u’(x) \;=\; 2x $$

$$ v(x) \;=\; sin(x), v’(x) \;=\; cos(x) $$

$$ ω(x) \;=\; e^x, ω’(x) \;=\; e^x $$

$$ \frac{d}{dx} [(x^2 + 1) . sin(x) . e^x] \;=\; (2x . sin(x) + (x^2 + 1) . cos(x) + (x^2 + 1) . sin(x)) . e^x \;=\; (2x sin(x) + cos(x)(x^2 + 1) + sin(x)(x^2 + 1)) . e^x $$
