A calculus text for engineering and science majors covering all the calculus core material, through vector integral calculus, plus some basic material in differential equations. Designed for either a one-year or a more leisurely paced three-semester sequence. Developed for the Engineering/Physics focused course, this new text covers only material essential for these students. This lean text can be covered in two semesters, or in a traditional three-semester course. It doesn't "skimp" on mathematical techniques, as these are critical for further courses. Key features include early coverage of vectors, optional graphing calculator material, optional computer algebra systems projects, a modeling focus, and discussion of differential equations material throughout the text.
