Erifunktsioonidega

Erifunktsioonidega refers to a concept in mathematics, particularly in the study of special functions. It translates from Estonian as "with special functions." This term is used to denote mathematical entities that are not elementary functions, meaning they cannot be expressed as a finite combination of algebraic operations, exponentials, logarithms, and trigonometric functions.

Special functions arise in various branches of mathematics, physics, engineering, and statistics. They often appear as solutions to differential equations that are fundamental to describing physical phenomena. Examples of well-known special functions include the Gamma function, Bessel functions, Legendre polynomials, and the Riemann zeta function. These functions possess unique properties and are characterized by their specific definitions, often involving integrals, infinite series, or recurrence relations.

The study of erifunktsioonidega involves understanding their properties, such as their convergence, asymptotic behavior, and relationships to other mathematical objects. They are crucial tools for modeling complex systems and solving problems that cannot be handled with basic functions alone. When encountering this term, it indicates a focus on these more advanced and specialized mathematical constructs.
