Solver: an interactive expression solver which can, in theory, numerically solve any equation versus any variable, using Newton's method. It may however fail to solve certain classes of equations depending on the expression format and starting values of the variables, so it is often necessary to rewrite the expression or experiment with initial ...
An example of using Newton–Raphson method to solve numerically the equation f(x) = 0. In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign.
The characteristic equation of a third-order constant coefficients or Cauchy–Euler (equidimensional variable coefficients) linear differential equation or difference equation is a cubic equation. Intersection points of cubic Bézier curve and straight line can be computed using direct cubic equation representing Bézier curve.
Equation solver (root finder) that can solve for any variable in an equation; Numerical integration for calculating definite integrals; Matrix operations (including a matrix editor, dot product, cross product and solver for simultaneous linear equations) Complex numbers (including polar coordinates representation) Vector functions
These purpose-built devices allow you to perform a wide range of calculations quickly—powerful models can even tackle complicated calculus equations and graph visual representations of functions.
The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.
As well as variables and programs, the user can store any number of equations in the calculator. "Equations" in this context means expressions ( f(x,...) ), equalities ( f 1 (x,...) = f 2 (x,...) ), and assignments (y = f(x,...)), which are each handled in different ways. Equations typically include named variables whose values are to be ...
Solving an equation f(x) = g(x) is the same as finding the roots of the function h(x) = f(x) – g(x). Thus root-finding algorithms can be used to solve any equation of continuous functions. However, most root-finding algorithms do not guarantee that they will find all roots of a function, and if such an algorithm does not find any root, that ...
