Trigonometric functions - Wikipedia
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle.They relate the angles of a triangle to the lengths of its sides.

Functional programming - Wikipedia
In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative programming paradigm, which means programming is done with expressions or declarations instead of statements.

Sass (Syntactically Awesome StyleSheets) Sass is an extension of CSS that adds power and elegance to the basic language. It allows you to use variables, nested rules, mixins, inline imports, and more, all with a fully CSS-compatible syntax.Sass helps keep large stylesheets well-organized, and get small stylesheets up and running quickly, particularly with the help of the Compass style library.
