There are three tracks through this text. The first is a course in Multivariable Calculus, suitable for the third semester in a standard calculus sequence. The second track is a sophomore level Vector Calculus class. The last track is for advanced undergraduates, or even beginning graduate students. At many institutions, a course in linear algebra is not a prerequisite for either multivariable calculus or vector calculus. Consequently, this book has been written so that the earlier chapters do not require many concepts from linear algebra. What little is needed is covered in the first section.
