Calculus: Numerical analysis - Essay Example

Both terms ‘differential’ and ‘integral’ constitute the vocabulary of calculus whose principle is widely understood in the applicability and purpose of differentiation and integration relevant for the life of everyday. In its existence and approach, calculus attempts to explore the grounds for the undefined nature of a function and designates a sensible understanding about up to which extent it would exist considering assumptions or applicable conditions. As in the rest of the significant fields in mathematics, calculus intellectuals had professed to work with a base knowledge of other math areas such as algebra and trigonometry to lay foundations and build on definitions, postulates, and theorems in conveying the purpose of the course and attain to its end thereafter.

Altogether, these calculus fundamentals which necessarily include applications of algebra, trigonometry, and analytic geometry are tools of advantage for students in the field of science and medical studies especially those involving multiple systems that deal with determination of various unknowns. During elementary level of math education, one merely learns that divisibility by zero is not in any way valid or possible and becomes content at treating such case as closed without entertaining its logic any further.

In calculus, however, though it is recognized that functions do have domains and ranges within which they remain defined, the subject goes beyond such point as extending concern to limits of a function. A function, according to calculus, is said to be continuous in an interval [a, b] if it is continuous and defined at any point within this same interval. If this initial condition is not satisfied, then the non-continuity implies that the function is also non-differentiable within [a, b]. Equivalently, the two-sided limits are stated in theorems that guide the study of whether a function’s limit does exist or not as x approaches a certain value and this requires tests to be conducted prior to conclusion.

These accounts are essential in discerning the significance of derivative which by definition pertains to an instantaneous rate of change or the slope of a tangent line to a curve at a point. While the concept of finding derivative is useful in applications that relate displacement, velocity, and acceleration, the reverse process of getting the antiderivative proves to be of crucial advantage in determining an area under the curve or a volume of a solid generated by revolving a strip of an element in a bounded region about a specific axis or line of revolution.

Since functions come in different types and complexities, calculus thereby exhibits a variety of ways by which integration may be carried out yet where no method seems adequate in evaluating a definite integral, numerical means of approximations are employed as a more flexible alternative. Limits apparently are a basic tool in setting up the framework of differentiation. Solving for derivatives in turn establishes applicability with problems on related rates which are extensively used even in engineering, physics, and other hard sciences that identify relevance in differentiating a function given a system with multiple variables.
