Differential Equations by Fort and Tomlinson is a comprehensive textbook that covers the fundamental concepts and techniques of differential equations. The book is designed for undergraduate students studying mathematics, physics, engineering, and other related fields. It provides a clear and concise introduction to the subject, starting with first-order differential equations and gradually progressing to higher-order equations and systems of equations.The book begins by introducing the basic concepts of differential equations, including the definition of a differential equation, the order of a differential equation, and the concept of a solution. It then covers first-order differential equations, including separable equations, linear equations, and exact equations. The authors also discuss applications of first-order differential equations in various fields, such as population dynamics, economics, and physics.The book then moves on to higher-order differential equations, including linear equations with constant coefficients, homogeneous equations, and nonhomogeneous equations. The authors also cover systems of differential equations, including matrix methods and numerical methods for solving systems of equations.Throughout the book, the authors provide numerous examples and exercises to help students understand the concepts and techniques of differential equations. The book also includes a comprehensive appendix that provides useful information on mathematical methods, including Laplace transforms, power series solutions, and numerical methods.Overall, Differential Equations by Fort and Tomlinson is an excellent textbook for undergraduate students studying differential equations. It provides a clear and concise introduction to the subject and covers all the essential topics in a comprehensive and accessible manner.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
