His mathematical interests are number theory and classical analysis. He is webmaster and newsletter editor for the MAA Southwestern Section and is an editor of the Missouri Journal of Mathematical Sciences. The use of “applications” in the title is exaggerated it means applications to other parts of mathematics, and not even a lot of those.Īllen Stenger is a math hobbyist and retired software developer. The book has the same sort of “calculus from an advanced standpoint” approach as Spivak’s Calculus on Manifolds: A Modern Approach to Classical Theorems of Advanced Calculus, although that book works only in Euclidean spaces, but does cover both integration and differentiation. There is no integration, and so no Stokes’s or Green’s theorems or any differential forms. Lagrange multipliers are presented through finding extrema on a manifold that satisfies the constraints. The book deals only with differential calculus, so the emphasis is on local behavior, extrema, and the inverse function theorem and implicit function theorem. Roughly the first third of the book develops the necessary theory of linear spaces, including a modest amount of functional analysis. The theory of partial derivatives gets developed along the way. Happily, most of the examples are from R 2 and R 3, and there are lots of pictures, so the level of abstraction is not overwhelming. The proofs are really not that different from the multivariable calculus found in careful textbooks such as Rudin’s Principles of Mathematical Analysis, but placing them in a more abstract context makes it easier to understand what’s going on. The present book is a 2012 unaltered reprint of the 1976 Van Nostrand Reinhold edition. This is intended as an upper-division undergraduate text, and it has lots of examples and challenging exercises. Differentiation and the Derivative Differentiation is the algebraic method of finding the derivative for a function at any point The derivative of a function is rate of change of Y axis with X(or slop at a point) 5. The generality pays off in the last chapter, that develops differential calculus on manifolds. Introduction Differential calculus is the study of rates of change of functions, using the tools of limits and derivatives. If f’(x) > 0, the function is increasing, and if f’(x) < 0, the function is decreasing.This is an interesting look at multivariable differential calculus, developed for functions on complete normed linear spaces rather than on R n. For example, the curve of the function goes from “facing down” to “facing up.” Finding inflection points involves a second derivative test, which we will not get to in this lesson. This is a point where a function has a change in the direction of curvature. To solve the non-homogenous differential equation, click the link: y (t) + y (t) sin (t). When f’(x) goes from negative values to 0 to positive values, a local maximum forms. For learning how to solve DFQs, use the Wolfram Alpha Step-by-Step Solutions pages. Our local maximum is higher than the points around it. It may also mean that the function has reached what is called a local maximum.In f(x), the local maximum is lower than all the points around it. A local maximum is a value of x where f’(x) changes from positive to negative and thus hits 0 along the way. It may mean that the function has reached a local maximum (or minimum).If f’(x) = 0, then the function is not changing. We can use the derivative of a function to determine where the function is increasing, decreasing, at a minimum or maximum value, or at an inflection point. ![]() The derivative is the slope of a tangent line at a specific point, and the derivative of a function f(x) is denoted as f’(x). ![]()
