The Leibniz Rule Calculator computes the nth derivative of the product of two functions using the Leibniz rule. This rule is essential in calculus for handling higher-order derivatives of products, making it a valuable resource for solving complex mathematical problems.
Formula of Leibniz Rule Calculator
The Leibniz rule is used to find the nth derivative of a product of two functions. The formula is:
where:
- n is the order of the derivative
- C(n, k) is the binomial coefficient, given by C(n, k) = n! / (k! * (n - k)!)
- (d^k/dx^k) v(x) is the k-th derivative of v(x)
- (d^(n - k)/dx^(n - k)) u(x) is the (n - k)-th derivative of u(x)
This formula helps in finding higher-order derivatives of products of functions.

Example of Leibniz Rule Calculator
Consider the functions u(x) = x^2 and v(x) = e^x. We want to find the 3rd derivative of their product using the Leibniz rule.
Using the formula:
d^3/dx^3 [x^2 e^x] = sum from k=0 to 3 of C(3, k) * (d^(3-k)/dx^(3-k)) x^2 * (d^k/dx^k) e^x
Calculating each term:
For k = 0: C(3, 0) * (d^3/dx^3) x^2 * e^x = 1 * 0 * e^x = 0
For-k = 1: C(3, 1) * (d^2/dx^2) x^2 * (d/dx) e^x = 3 * 2 * e^x = 6e^x
For k = 2: C(3, 2) * (d/dx) x^2 * (d^2/dx^2) e^x = 3 * 2x * e^x = 6xe^x
For-k = 3: C(3, 3) * x^2 * (d^3/dx^3) e^x = 1 * x^2 * e^x = x^2 e^x
Summing all terms: d^3/dx^3 [x^2 e^x] = 0 + 6e^x + 6xe^x + x^2 e^x
