Introduces the and singular perturbation problems. Part 2: Asymptotic Analysis of Exponential Integrals
In the world of applied mathematics, there exists a fascinating paradox: many of the most important problems have exact solutions that are either impossible to find or too complicated to use. How do physicists model the shockwave of an explosion? How do engineers predict the flutter of a wing at high speeds? How do climatologists project sea levels a century from now?

"Applied Asymptotic Analysis" by Peter D. Miller is a valuable resource for anyone interested in learning about asymptotic methods. By working through the exercises and applying the techniques presented in the book, you'll gain a deeper understanding of asymptotic analysis and its applications.
"As an engineer, I found Miller hard at first. But once I reviewed complex variables, the WKB chapter saved my project on acoustic waveguides. A permanent reference on my desk." — Introduces the and singular perturbation problems

For small ( \epsilon > 0 ), the solution jumps rapidly near ( x=0 ). A naive expansion fails. Miller teaches you to identify the boundary layer at ( x=0 ), stretch the coordinate (( X = x/\epsilon )), solve the inner and outer equations separately, and match them using a common limit.
