This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. This text is designed for a three-semester or four-quarter calculus course (math, engineering, and science majors). Thomas’ Calculus: Early Transcendentals, Thirteenth Edition, introduces readers to the intrinsic beauty of calculus and the power of its applications. For more than half a century, this text has been revered for its clear and precise explanations, thoughtfully chosen examples, superior figures, and time-tested exercise sets. With this new edition, the exercises were refined, updated, and expanded—always with the goal of developing technical competence while furthering readers’ appreciation of the subject. Co-authors Hass and Weir have made it their passion to improve the text in keeping with the shifts in both the preparation and ambitions of today's learners.
