Introduction. Teaching multivariable calculus, which is the study of curves and surfaces in space, can definitely be enhanced by using the 3-D graphics, and the spacial vector capabilities of Maple. This book provides a new look at vector calculus by integrating the use of Maple with the traditional vector calculus curriculum. Close examination of this text will show that while the method of presenting the topics makes extensive use of Maple, this innovation has been introduced without significantly revising the traditional topics. We have deliberately decided to guide instructors and students through material which is familiar to the instructors, to investigate and compare the capabilities of Maple with the more traditional presentation of vector calculus. As a result, this text can be used in place of a traditional vector calculus text without causing any radical changes in the subject matter.
