In fact, a calculator uses some kind of algorithm based on the basic operations not only to calculate trigonometric values, but also square roots, values of hyperbolic functions and others. The branch of mathematics called numerical methods studies and develops these algorithms. It is an interesting field of mathematics, and one that has lots of applications.

In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions ) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. #Geometry calculator sin cos tan series.#Geometry calculator sin cos tan how to.
