Multivariable Calculus is an introduction to the basic concepts and tools of multivariable calculus, which are usually covered in the second and third parts of the undergraduate calculus course sequence. The book started as series of lecture notes for the MAT2322 University of Ottawa course (Calculus for Engineers). Since the content became large and complete, I decided to convert the lecture notes into a book that can be used as a textbook and a reference for all students of North-American universities.

Fabrizio Donzelli earned his BS in Physics from the Universita' degli studi di Milano (Italy) and his Ph. D. in Mathematics from the University of Miami (Florida). He started his career as a researcher by working in the field of affine algebraic geometric, and then expanded his research to the field of numerical analysis, focusing on stochastic and deterministic domain decomposition solution methods of partial differential equations. The author has almost two decades of teaching experience of undergraduate and graduate courses in university of Canada and United States. His interest and passion for education does not limit to university: he works as well in the tutoring business, providing assistance to students from grade 4 to grade 12.
