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.
