vahefunktsiooni
Vahefunktsiooni, in Estonian, translates to "difference function" or "difference operator." It is a mathematical concept used to describe the change in a function's value when its input is altered by a specific increment. This concept is fundamental in calculus and numerical analysis, forming the basis for understanding derivatives and discrete approximations of continuous functions.
The general form of a difference function is denoted as $\Delta f(x)$, which represents $f(x+h) - f(x)$,
The concept of a difference function is closely related to the definition of a derivative. As the
Beyond calculus, difference functions are vital in numerical methods for approximating solutions to differential equations and
