Partial Differential Equations: An Essay Towards An Entirely New Method Of Integrating Them is a book written by Samuel Earnshaw and originally published in 1871. The book is a comprehensive guide to the study of partial differential equations, which are mathematical equations that involve partial derivatives of an unknown function of several variables. In this book, Earnshaw presents a new method for integrating partial differential equations, which he claims is simpler and more efficient than existing methods. He begins by introducing the basic concepts and terminology of partial differential equations, and then goes on to explain his new method in detail. The book is divided into four parts. In the first part, Earnshaw provides an introduction to partial differential equations and their applications. In the second part, he presents his new method of integrating partial differential equations, which he calls the ''method of characteristics.'' This method involves finding a set of curves, called characteristics, along which the solution to the equation is constant. In the third part of the book, Earnshaw applies his method to a variety of specific types of partial differential equations, including linear equations, equations of the first order, and equations with variable coefficients. He also discusses the use of his method in solving boundary value problems. In the final part of the book, Earnshaw presents a series of examples and exercises to help readers practice and apply his method. He also includes a number of appendices with additional mathematical background and technical details. Overall, Partial Differential Equations: An Essay Towards An Entirely New Method Of Integrating Them is a seminal work in the field of partial differential equations, and a valuable resource for anyone interested in this subject.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
