New and updated features of this title
Updated extensive content coverage, exercises, and worked examples
NEW! A new Chapter 8 considers concave and convex functions of one variable, including results on supergradients of concave functions and subgradients of convex functions that play a key role in the theory of optimisation.
NEW! A new Chapter 16 on multiple integrals.
REVISED! Chapter 13 has been extended to include eigenvalues and quadratic forms.
REVISED! Numerous exercises and worked examples throughout each chapter allow your students to practice skills and improve techniques.
REVISED! Review exercises at the end of each chapter to test your students' understanding of a topic before they progress with confidence.
A revised structure enhances student engagement
NEW! Matrix algebra is introduced earlier in this edition and now precedes the chapter on multivariate calculus. This allows new tools to be used in the treatment of multivariate calculus and in the last four chapters, now devoted exclusively to optimization.
NEW! The chapter on constrained optimisation has been divided to form two new chapters: Chapters 18 & 20.
REVISED! Solutions to exercises are provided in the book and online, breaking down the steps needed to arrive at the correct answer.
