Description

Essentials of Complex Analysis is an introduction to the fundamental concepts in complex analysis, suitable for a first course at the undergraduate level. The book covers the elementary functions, the Cauchy–Riemann equations, complex integration, Cauchy's theorem and the residue theorem. It ends with a series of applications of complex analysis to hydrodynamics, transcendental equations, elliptic functions and more.

Each chapter is accompanied by exercises and solutions, and the text concludes with a review of the material and a sample final exam. Students can download a free, interactive ebook version to engage with live Wolfram Language code.

Additional materials, including videos, interactive demonstrations, quizzes and exams can be found online in the companion Wolfram U course.
