| Complex numbers The calculator displays complex number and its conjugate on the complex plane, evaluate complex number absolute value and principal value of the argument . It also demonstrates elementary operations on complex numbers. |
| 3d coordinate systems Transforms 3d coordinate from / to Cartesian, Cylindrical and Spherical coordinate systems. |
| 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. |
| Is a point in a triangle? The calculator determines if an arbitrary point lies inside 2D triangle. The triangle is defined by 3 cartesian coordinate pairs. |
| Equation of a line given two points This online calculator finds the equation of a line given two points on that line, in slope-intercept and parametric forms |
| Equation of a circle calculator This circle equation calculator displays a standard form equation of a circle, a parametric form equation of a circle, and a general form equation of a circle given the center and radius of the circle. Formulas can be found below the calculator. |
| Equation of a circle passing through 3 given points This online calculator finds a circle passing through three given points. It outputs the center and radius of a circle, circle equations and draws a circle on a graph. The method used to find a circle center and radius is described below the calculator. |
| Find the distance and midpoint between two points This online calculator finds the distance and midpoint between two points in cartesian coordinates. |
| Covariance calculator This online calculator computes covariance between two discrete random variables. It also shows the expected value (mean) of each random variable. You can find the formula used for the calculation of covariance below the calculator. |
| Quick Sum Calculator This online calculator sums up entered numbers. Any symbol what is not a digit, for example, a space, a comma, a semicolon, etc, serves as a separator. It is useful when you need to sum up several numbers but do not have speadsheet program at hand. Use the dot symbol as separator for the decimal part of the number if you need to. |
| The discriminant This online calculator calculates the discriminant of the quadratic polynomial, as well as higher degree polynomials |
| Triangle Area Calculator This calculator is designed to find the area of a triangle using different formulas, depending on the available information about the triangle. |
| Sphere Volume and Radius Calculator This calculator is a two-in-one tool that can be used to find the volume of a sphere given its radius, or the radius of a sphere given its volume. |
| Equilateral triangle This online calculator calculates characteristics of the equilateral triangle: the length of the sides, the area, the perimeter, the radius of the circumscribed circle, the radius of the inscribed circle, the altitude (height) from single known value |
| Equation of a plane passing through three points This online calculator calculates the general form of the equation of a plane passing through three points |
| 3D Vector Dot Product Calculator This online calculator calculates the dot product of two 3D vectors |
| Magnitude of a Vector This online calculator calculates the magnitude of a vector |
| Angle between two vectors This online calculator finds the angle between two vectors |
