| Newton's method This online calculator implements Newton's method (also known as the Newton–Raphson method) for finding the roots (or zeroes) of a real-valued function. |
| Playfair cipher This online calculator encrypts and decrypts a message given Playfair cipher keyword. Non-alphabetic symbols (digits, whitespaces, etc.) are ignored. |
| Polynomial Greatest Common Divisor The calculator gives the greatest common divisor (GCD) of two input polynomials. |
| Squarefree polynomial factorization The calculator extracts square factors from the input polynomial. |
| Polynomial root isolation The calculators isolates real roots of the input univariate polynomial using Sturm and VAS-CF methods. |
