Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They are usually peer-reviewed or refereed. Content typically takes the form of articles presenting original research, review articles, and book reviews. The purpose of an academic journal is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge, and perfecting all Philosophical Arts, and Sciences.</p> CALCULUS – DIFFERENTIAL, INTEGRAL, AND INFINITE 2021-04-05T06:56:58+00:00 Garry Alfonsius <p>Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.</p> <p>It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while integral calculus concerns accumulation of quantities, and areas under or between curves. These two branches are related to each other by the fundamental theorem of calculus, and they make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.</p> 2021-04-05T00:00:00+00:00 Copyright (c) 2021 Universal Journal
