When a viscous fluid flows past a flat plate at high speed, the Navier-Stokes equations are impossible to solve exactly. Using singular perturbation theory (Chapter 5 of Miller), one divides the flow into a thin near the plate (where viscosity matters) and an outer region (where it doesn’t). Matching the two solutions yields the famous Blasius solution.
To give you a taste of why this book is valuable, consider a simple singular perturbation problem: You will find unauthorized scans on file-sharing sites
For ( \int_a^b e^i\lambda \phi(x) f(x) dx ), ( \phi ) real, stationary point ( \phi'(c)=0 ): [ I(\lambda) \sim f(c) e^i\lambda \phi(c) + i \frac\pi4 \textsgn(\phi''(c)) \sqrt\frac2\pi\lambda ]

Miller introduces the theory of asymptotic expansions, contrasting them with Taylor series. Key concepts include: Defining notation rigorously.
