Polynomial root isolation
The calculators isolates real roots of the input univariate polynomial using Sturm and VAS-CF methods.
Polynomial roots
The calculator solves polynomial roots of any degree. For small degree polynomials analytic methods are applied, for 5-degree or higher the polynomial roots are estimated by numerical method.
Z-score / Standard score
This online calculator computes the standard score of a raw score from the given mean of the population and the standard deviation of the population.
P-value
This online calculator calculates p-value for one sided and two sided tests given the z-score

Two arguments arctangent
The calculator gives an angle between positive axis x and the ray to the given point from point 0. The result corresponds to atan2 function, implemented in many computer languages and math libraries.
Vector Addition Calculator
This online calculator performs vector addition and displays vectors and vector sum graphically.
Synthetic division
Synthetic division is a simplified way of dividing a polynomial using only the coefficients of the terms in the polynomial. It is a shortcut method that avoids the need for long division or the use of the polynomial remainder theorem.
