Introduction to trigonometric functions.

Trigonometric functions are a class of functions in mathematics that belong to the transcendental functions of elementary functions. Their essence is a mapping between a set of arbitrary angles and a set of variables with a ratio. The usual trigonometric function is defined in a planar Cartesian coordinate system, which defines the entire field of real numbers.

Another definition is in a right triangle, but not completely. Modern mathematics describes them as the limits of an infinite series of numbers and the solution of differential equations, extending their definition to complex systems.

Due to the periodic nature of trigonometric functions, it does not have an inverse function in the sense of a single-valued function.

Trigonometric functions have important applications in complex numbers. In physics, trigonometric functions are also commonly used tools.

inverse tangent) is a mathematical term for an inverse trigonometric function.

The inverse function of the tangent function y=tanx in the open interval (x (-2, 2)) is denoted as y=arctanx or y=tan-1x, which is called the arctangent function. It represents the angle at which the tangent on (- 2, 2) is equal to x, i.e., tan(arctan x)=x, which is the domain of the definition of the arctangent function.
