Mathematical Foundation
The Real Root Isolation Calculator is based on Sturm’s theorem, a peer-reviewed method for determining the number of real roots of a polynomial in a given interval. For a polynomial P(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₀, Sturm’s theorem constructs a Sturm sequence:
- P₀(x) = P(x)
- P₁(x) = P'(x) (first derivative)
- Pₖ(x) = -remainder(Pₖ₋₂(x) / Pₖ₋₁(x))
The number of real roots in an interval [a, b] is the difference in the number of sign changes in the Sturm sequence evaluated at x = a and x = b. The tool uses bisection to refine intervals, ensuring each contains exactly one root, aligning with established algebraic methodologies.
Applications in Real-World Scenarios
