2 Annotated Table of Contents.For your convenience, we have annotated this table of contents in order to highlight some specific areas of the text where traditional presentation has been rejuvenated with what we believe to be new and innovative approaches. Preface xi 0 Preliminaries The properties and graphs of linear, polynomial and trigonometric functions are presented, and some simple mathematical models involving these functions are introduced. Examples are given of numerical and graphical and algebraic approaches to problem solving in settings that do not require the use of sophisticated technology. 0.1 Graphs and Equations Functions 9 In Example 2, a quadratic mathematical model of a water balloon is introduced and approached numerically, graphically and algebraically. 0.3 The Straight Line and Linear Functions 19 - Example 4 involves developing d linear model for an automobile trip; numerical, graphical and algebraic methods are used to answer some questions. 0.4 The Trigonometric Functions 27 Example 5 demonstrates how graphical/numerical solutions to equations involving trigonometric functions are related to algebraic solutions involving inverse trigonometric functions. 0.5 Chapter Review 38 ~ "^. Calculus: A First Look 41 Limits, derivatives and the exponential and logarithmic functions are introduced and explored. Numerical estimation of limits and derivatives is emphasized. 1.1 Introduction to Limits: Part I 41 This section introduces a method of estimating limits numerically and of determining the accuracy of the estimate. Lab 1: Exploring Limits Introduction to Limits: Part II 52 Limits involving infinity are approached numerically. Continuity is introduced and, in Example 4, discussed in the context of a practical mathematical model of the voltage supplied by a battery. 1.3 The Derivative: Two Problems with One Theme 60 Derivatives and instantaneous velocity are estimated numerically, and some simple derivative formulas are found. 1.4 Exponential Functions 70 The natural exponential function is developed as the exponential function whose slope and y-coordinate are the same at each point.

Lab 10: Area Functions and the Fundamental Theorem of Calculus The Fundamental Theorem of Calculus 321 Exact definite integrals are found by hand and with the use of computer algebra. 5.6 More Properties of the Definite Integral Substitution Chapter Review 345 Applications of the Integral The definite integral is applied to numerous situations. 6.1 The Area of a Plane Region Volumes of Solids: Slabs, Disks, Washers Length of a Plane Curve 366 Parametric representation of curves is introduced, including calculator and computer graphing of such curves. In the lab project at,the end of the section, a problem involving a guitar string is used to show when it is helpful to be able to evaluate a definite integral exactly, and when a numerical approximation is necessary. Lab 11: Arc Length Work Moments; Center of Mass Chapter Review 392 Transcendental Functions and Differential Equations 395 The exponential, logarithmic and trigonometric functions are explored in greater detail, as well as the relationship between exponential functions and differential equations. 1.1 Inverse Functions and Their Derivatives A Different Approach to Logarithmic and Exponential Functions 402 This section shows that by defining the natural log function using a definite integral, and the natural exponential function as its inverse, it now becomes relatively easy to demonstrate several properties of the log and exponential functions that were previously left unproven. In the lab at the end, a model of falling objects that encounter air resistance is developed andfitto real data taken of a falling balloon. Lab 12: Falling Objects General Exponential and Logarithmic Functions Exponential Growth and Decay 419 This section explores the relationship of the exponential function to certainfirst-orderdifferential equations. 7.5 Numerical and Graphical Approaches to Differential Equations 426 Euler's method of numerically solving differential equations is presented, and the numerical methods built in to some calculators and computer algebra systems are investigated. In the lab at the end of the section, advantages and disadvantages of exact versus numerical solutions are discovered in the context of retirement planning. Lab 13: Planning Your Retirement Numerically The Trigonometric Functions and Their Inverses The Hyperbolic Functions and Their Inverses Chapter Review 451

Both exact and numerical methods are presented and compared. 9.1 Infinite Sequences and Dynamical Systems 513 Explicitly and recursively defined sequences are given equal emphasis. The lab at the end introduces a discrete model of population growth, which parallels the continuous model from Lab i5 and leads to the study of chaotic systems.
