Div, Grad, Curl, and All that

Book excerpt: Since its publication in 1973, a generation of science and engineering students have learned vector calculus from Dr. Schey's Div, Grad, Curl, and All That. This book was written to help science and engineering students gain a thorough understanding of those ubiquitous vector operators: the divergence, gradient, curl, and Laplacian. The Second Edition preserves the text's clear and informal style, moderately paced exposition, and avoidance of mathematical rigor which have made it a successful supplement in a variety of courses, including beginning and intermediate electromagnetic theory, fluid dynamics, and calculus.
