Using A Calculator Find The Zeros Of The Polynomial Function

Introduction & Importance

Finding the zeros of a polynomial function is a crucial step in understanding and analyzing polynomial equations. This calculator helps you determine the zeros, also known as roots, of a polynomial function efficiently.

How to Use This Calculator

1. Select the degree of the polynomial.
2. Enter the coefficients of the polynomial in the order of decreasing powers (a_n, a_n-1, …, a₀).
3. Click the “Calculate” button.

Formula & Methodology

The calculator uses the Bisection Method to find the zeros of the polynomial function. The method is based on the Intermediate Value Theorem and involves repeatedly dividing an interval in half until the desired precision is achieved.
