Active Calculus Multivariable is the continuation of Active Calculus to multivariable functions. The Active Calculus texts are different from most existing calculus texts in at least the following ways: the texts are free for download by students and instructors in .pdf format; in the electronic format/ graphics are in full color and there are live html links to java applets; the texts are open source/ and interested instructors can gain access to the original source files upon request; the style of the texts requires students to be active learners — there are very few worked examples in the texts/ with there instead being 3-4 activities per section that engage students in connecting ideas/ solving problems/ and developing understanding of key calculus concepts; each section begins with motivating questions/ a brief introduction/ and a preview activity/ all of which are designed to be read and completed prior to class; the exercises are few in number and challenging in nature.
