Differentsiaalia
Differentsiaalia is a term primarily used in Estonian mathematics to refer to the concept of a differential, or more broadly, the differential calculus. It encompasses the study of rates of change and accumulation, fundamental to understanding how functions behave. The core ideas of differentsiaalia involve differentiation, which is the process of finding the derivative of a function, and integration, which is the process of finding the antiderivative.
The derivative of a function at a particular point represents the instantaneous rate of change of that
Integration, on the other hand, is concerned with calculating the area under the curve of a function.
