INFINITESIMAL CALCULUS Meaning and
Definition
-
Infinitesimal calculus is a branch of mathematics that focuses on the study of change and motion through the concept of infinitesimals. It is a fundamental tool in the field of calculus, which deals with the analysis of continuous change and the properties of functions. Infinitesimal calculus consists of two main branches, known as differential calculus and integral calculus.
Differential calculus involves the study of the instantaneous rate of change of a quantity and the concepts of derivatives and differentials. It enables mathematicians to determine how functions change as their input variables vary. Derivatives are used to calculate slopes of tangent lines to curves, rates of change, and critical points of functions. Differential calculus is crucial in various fields, including physics, engineering, and economics.
Integral calculus, on the other hand, focuses on the accumulation of quantities and the concept of integration. It allows mathematicians to calculate the total change in a quantity by summing up infinitesimally small changes. Integrals are used to find areas under curves, solve mathematical equations, and compute averages. Integral calculus is widely applied in physics, economics, and statistics.
Infinitesimal calculus revolutionized mathematics and scientific studies by providing powerful tools to analyze and model continuous change. Its concepts and techniques have become essential in understanding the fundamental laws of nature and solving complex mathematical problems. Moreover, it laid the foundation for more advanced branches of mathematics, such as differential equations, Fourier analysis, and complex analysis.

Etymology of INFINITESIMAL CALCULUS
The word "infinitesimal calculus" has its roots in Latin and Greek.
- "Infinitesimal" comes from the Latin word "infinitesimus", meaning "infinite, immeasurably small". It is formed from the prefix "in-" meaning "not" or "un-" and the word "finis" meaning "boundary" or "limit".
- "Calculus" comes from the Latin word "calculus", meaning "small stone" or "pebble". It referred to the method of calculating using pebbles on an abacus.
The term "infinitesimal calculus" is used to describe the branch of mathematics that deals with limits, continuity, derivatives, integrals, and infinite series. The combination of "infinitesimal" meaning very small and "calculus" meaning calculation or method of calculation aptly represents the concepts and techniques of this mathematical discipline.
