Understanding the Product Rule Calculator: 

In the realm of calculus, the Product Rule stands as a fundamental principle enabling the differentiation of functions that multiply together

The Product Rule Calculator stands out as one of the most useful tools for assisting with complex mathematical issues. This page explores this calculator's depths, illuminating its importance, capabilities, and practical applications.

What is Product Rule?

The Product Rule in calculus deals with finding the derivative of a product of two functions. Mathematically, it is represented as:

\( \frac{d}{dx} (u \cdot v) = u'v + uv' \)


  • \( u(x) \) and \( v(x) \) are two differentiable functions with respect to \( x \).
  • \( u' \) denotes the derivative of \( u(x) \) with respect to \( x \).
  • \( v' \) denotes the derivative of \( v(x) \) with respect to \( x \).

This rule allows us to find the derivative of the product of two functions by taking the derivative of one function, multiplying it by the other, and then adding the product of the two functions' derivatives.

Product Rule Formula:

The Product Rule in calculus is given by:

\( (uv)' = u'v + uv' \)


Let's say we have two functions \( u(x) = 3x^2 \) and \( v(x) = \sin(x) \).

According to the Product Rule:

\( (u \cdot v)' = u'v + uv' \)

\( (3x^2 \cdot \sin(x))' = (6x \cdot \sin(x)) + (3x^2 \cdot \cos(x)) \)

\( = 6x \sin(x) + 3x^2 \cos(x) \)

Applying the Derivative Product Rule:

The Derivative Product Rule is used to find the derivative of a product of two functions. Here's how to apply it:

Step 1: Identify the functions

Consider two differentiable functions \( u(x) \) and \( v(x) \).

Step 2: Write down the functions and their derivatives

Express the functions \( u(x) \) and \( v(x) \) and find their derivatives \( u' \) and \( v' \) with respect to \( x \).

Step 3: Apply the Product Rule formula

Use the formula \( \frac{d}{dx} (u \cdot v) = u'v + uv' \) to compute the derivative of the product of the functions.

Step 4: Substitute the derivatives into the formula

Substitute the calculated values of \( u' \), \( v' \), \( u(x) \), and \( v(x) \) into the formula and simplify to find the derivative of \( u(x) \times v(x) \).

Step 5: Simplify the expression

Simplify the resulting expression, if possible, to obtain the final derivative.

By following these steps and using the Product Rule formula, you can effectively find the derivative of the product of two functions.

What is the product rule of exponents?

The product rule of exponents simplifies the multiplication of exponential expressions with the same base. It states that when multiplying two exponential terms with the same base, you can keep the base the same and add the exponents together.

Mathematically, if you have expressions of the form \(a^m \times a^n\) (where \(a\) is a non-zero real number and \(m\) and \(n\) are any real numbers), the product rule of exponents can be expressed as:

\( a^m \times a^n = a^{m+n} \)


  • \(a\) represents the base.
  • \(m\) and \(n\) are the exponents.

This rule simplifies the multiplication of exponential terms by combining them into a single term with the same base raised to the sum of the exponents.

Examples of Product Rule of Exponents:

  1. Example 1: \(2^3 \times 2^5\)

    \(2^3 \times 2^5 = 2^{3+5} = 2^8 = 256\)

  2. Example 2: \(5^4 \times 5^2\)

    \(5^4 \times 5^2 = 5^{4+2} = 5^6 = 15625\)

  3. Example 3: \((-3)^3 \times (-3)^6\)

    \((-3)^3 \times (-3)^6 = (-3)^{3+6} = (-3)^9 = -19683\)

  4. Example 4: \((-2)^{-4} \times (-2)^2\)

    \((-2)^{-4} \times (-2)^2 = (-2)^{-4+2} = (-2)^{-2} = \frac{1}{(-2)^2} = \frac{1}{4}\)

  5. Example 5: \(10^7 \times 10^{-3}\)

    \(10^7 \times 10^{-3} = 10^{7+(-3)} = 10^4 = 10000\)
