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.

a function at x0 leads to division by zero, which is undefined. We encountered this last circumstance when seeking the instantaneous rate of change in y by considering the quotient function ¢y>h for h closer and closer to zero. Here’s a specific example where we explore numerically how a function behaves near a particular point at which we cannot directly evaluate the function. y 2 2 y ϭ f (x) ϭ x Ϫ 1 xϪ 1 1 –1 0 1 x EXAMPLE 1 How does the function y ƒsxd = x2 - 1 x - 1 behave near x

Make tables of values of ƒ at values of x that approach x0 = 1 from above and below. Does ƒ appear to have a limit as x : 1 ? If so, what is it? If not, why not? b.

Effectively, F is the function ƒ with its point of discontinuity at x = 2 removed. lim FIGURE 2.45 (a) The graph of ƒ(x) and (b) the graph of its continuous extension F(x) (Example 10). Intermediate Value Theorem for Continuous Functions Functions that are continuous on intervals have properties that make them

increasingly steep (Figure 3.2). We see this situation again as a : 0 - . As a moves away from the origin in either direction, the slope approaches 0 and the tangent levels off to become horizontal. Rates of Change: Derivative at a Point The expression ƒsx0 + hd - ƒsx0 d , h h Z 0 is called the difference quotient of ƒ at x0 with increment h. If the difference quotient has a limit as h approaches zero, that limit is given a special name and notation. DEFINITION The derivative of a function ƒ

In this chapter we review what functions are and how they are pictured as graphs, how they are combined and transformed, and ways they can be classified. We review the trigonometric functions, and we discuss misrepresentations that can occur when
