This edition presents core ideas in the calculus of finite differences, interpolation, and numerical quadrature. It combines theory with worked examples and practical rules, helping you compute values, tabulate functions, and approximate integrals with proven methods.

Readers will see how to build tables, apply difference operators, and use formulas for accurate results. The text covers a range of technique—from generating fundamental values for logarithm tables to applying Gauss’ method of quadrature—along with guidance on error and accuracy.

Understand the difference operator and how higher differences become constant for polynomials.

Learn interpolation and tabulation techniques for polynomials and non-polynomial functions.

Explore several numerical integration rules, including trapezoidal, Simpson’s, Three-Eighths, and Gauss’ method.

See practical examples and instructions for estimating areas and distances from data.

Ideal for students and professionals applying numerical methods in engineering, physics, or applied mathematics.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
