My multivariable calculus textbook is on Amazon at the link below. See also the book webpage.

On this YouTube channel, courses are organized in Playlists. The Playlist for the above linked book is called Multivariable Calculus -- to accompany text by Clark Bray. See also my Duke courses on (1) multivariable calculus and (2) linear algebra and differential equations.

Teaching math at Duke is my primary professional focus, and these recordings are from my Duke lectures. I hope you will find them useful!
