lisafunktsioon

Lisafunktsioon is a term used in Estonian to describe a function added to a system, model, or calculation to extend its capability or to aid in solving a problem. The word combines lisa (add or supplementary) with funktsioon (function), indicating its role as an auxiliary or supplementary element rather than a core component.

In mathematics and analysis, lisafunktsioon often refers to an auxiliary function introduced to simplify a problem. It can be used to facilitate substitutions, to separate difficult parts of a calculation, or to capture a particular behavior within a proof or solution. For example, a lisafunktsioon may be defined to transform an integral into a more tractable form or to satisfy boundary conditions in differential equations. In these contexts, the lisafunktsioon is typically defined specifically for the task at hand and may be eliminated or replaced once the main result is obtained.

In software, data science, and engineering, lisafunktsioon denotes a function added through libraries, plugins, or modules to extend a program’s capabilities. Such functions are optional and not part of the core language or framework, enabling users to perform additional operations such as advanced statistics, signal processing, or custom data transformations.

Relation to other terms: lisafunktsioon is closely related to abifunktsioon (auxiliary function) and other extension concepts. While usage varies by discipline, the common idea is a function that supports or enhances a primary objective without being a fundamental part of the original formulation.
