A Cubic Equation Solver for calculating the roots of cubic polynomials based on the Cardano's mathematical formula. Roots are rounded to two decimal places. if A = 0 the roots are estimated by an ...

Further, we show that this result over polynomials can be used to settle (positively) the sum of square roots problem for a special class of integers: Suppose each integer ai is of the form, ai = Xdi ...

Summary Imagine a sphere with its equator inscribed in an equilateral triangle. This Saturn-like figure will help us understand from where Cardano’s formula for finding the roots of a cubic polynomial ...

It has been pointed out that the notion of the sum of roots can be utilized for solving (parametric) polynomial spectral factorization. This paper reveals another aspect of the sum of roots as an ...

Roots of unity are the roots of the polynomials of the form xn – 1. For example, when n = 2, this gives us the quadratic polynomial x2 – 1. To find its roots, just set it equal to 0 and solve: x2 – 1 ...

The paper describes an application that allows to visualize four-dimensional graphs of a complex variable function. Three coordinates of the graph are Cartesian, and fourth is the parametric ...
