poly-derivative

Computes the derivative a polynomial. Formally the same thing as multiplying by the index and shifting left.

Example

Compute the derivative of the polynomial 1 + 2*x + 3*x^2 + 4*x^3:

console.log(require("poly-derivative")([1, 2, 3, 4]))

Output

[ 2, 6, 12 ]

Install

Install using npm:

npm install poly-derivative

API

require("poly-derivative")(coeffs)

Computes the derivative of a polynomial, with coefficients represented in increasing order.

• coeffs are the coefficients of the polynomial

Returns The derivative of the polynomial
