A First Look at Perturbation Theory - (Dover Books on Physics) 2nd Edition by James G Simmonds & James E Mann (Paperback)

This book provides a comprehensive introduction to perturbation theory for engineering and physical science undergraduates.

The author explains methods for obtaining approximate solutions to mathematical problems by exploiting small, dimensionless parameters.

The text covers various techniques for handling perturbations in differential equations and provides practical examples of how to apply these methods to real-world problems.

With a focus on the why along with the how, this book is an essential resource for anyone looking to gain a deeper understanding of mathematical problem-solving.
