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. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

The @classmethod form is a function decorator – see the description of function definitions in Function definitions for details.. It can be called either on the class (such as C.f()) or on an instance (such as C().f()).The instance is ignored except for its class.

Less extends CSS with dynamic behavior such as variables, mixins, operations and functions. Less runs on both the server-side (with Node.js and Rhino) or client-side (modern browsers only).
Functional programming - Wikipedia
Higher-order functions are functions that can either take other functions as arguments or return them as results. In calculus, an example of a higher-order function is the differential operator /, which returns the derivative of a function .. Higher-order functions are closely related to first-class functions in that higher-order functions and first-class functions both allow functions as ...
