Inverse sine

Writing functions:

arcsin(x)

Returns the inverse of that value, which returns the sine, so arcsin(sin(x))=x.

The arcsine is a mathematical function that is the inverse of the sine function. It is denoted as arcsin(x) or sin^(-1)(x). The arcsine is defined for all values of x from the interval [-1, 1]. The graph of the arcsine function has the form of a symmetric curve bounded on the segment [-?/2, ?/2].

The use of the arcsine function is often found in various fields of science and technology. For example, in trigonometry, the arcsine is used to solve equations and find angles, as well as to approximate complex functions. In physics, the arcsine is used in the study of waves and vibrations, as well as in the analysis of electric and magnetic fields.

The use of the arcsine function is also widespread in computer science, data analytics, and engineering. It helps in modeling and approximating data, calculating angles and distances, as well as solving various optimization problems.

As a result, the arcsine function is an important tool for mathematicians, physicists, engineers and computer science specialists, allowing them to effectively solve a variety of problems and apply mathematical methods in practical tasks.
