An Introduction To The Differential Calculus By Means Of Finite Differences is a book written by Robert R. Buchanan and published in 1905. The book introduces the concept of differential calculus through the use of finite differences, which is a method of approximating derivatives by using a difference quotient. The book covers topics such as the basic principles of finite differences, the differentiation of algebraic functions, the differentiation of trigonometric functions, and the differentiation of exponential and logarithmic functions. The book also includes exercises and examples to help readers understand the concepts presented. This book is a valuable resource for students and professionals in the field of mathematics who are interested in learning about differential calculus through the use of finite differences.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
