Book Preface
The fine art of education, Mark Van Doren said, is the art of profitable discovery. I have tried to write a volume that assists students in discovering calculus—both for its practical ability and its surprising beauty. In this edition, equally in the first vii editions, I aim to convey to the pupil a sense of the utility of calculus and develop technical competence, merely I besides strive to give some appreciation for the intrinsic dazzler of the subject. Newton undoubtedly experienced a sense of triumph when he made his swell discoveries. I want students to share some of that excitement.
The accent is on understanding concepts. I think that well-nigh everybody agrees that this should exist the primary goal of calculus instruction. In fact, the impetus for the current calculus reform movement came from the Tulane Conference in 1986, which formulated equally their first recommendation:
Focus on conceptual understanding.
I have tried to implement this goal through the Rule of 3: "Topics should be presented geometrically, numerically, and algebraically." Visualization, numerical and graphical experimentation, and other approaches have inverse how we teach conceptual reasoning in primal ways. More than recently, the Rule of Three has been expanded to become the Rule of Four by emphasizing the exact, or descriptive, indicate of view as well.
In writing the eighth edition my premise has been that information technology is possible to achieve conceptual understanding and still retain the all-time traditions of traditional calculus. The book contains elements of reform, merely inside the context of a traditional curriculum.
I have written several other calculus textbooks that might exist preferable for some instructors. Well-nigh of them as well come up in single variable and multivariable versions.
● Calculus: Early on Transcendentals, Eighth Edition, is similar to the present textbook except that the exponential, logarithmic, and changed trigonometric functions are covered in the beginning semester.
● Essential Calculus, 2d Edition, is a much briefer book (840 pages), though it contains almost all of the topics in Calculus, Eighth Edition. The relative brevity is achieved through briefer exposition of some topics and putting some features on the website.
Essential Calculus: Early on Transcendentals, Second Edition, resembles Essential Calculus, simply the exponential, logarithmic, and inverse trigonometric functions are covered in Chapter three.
● Calculus: Concepts and Contexts, Fourth Edition, emphasizes conceptual understanding fifty-fifty more strongly than this book. The coverage of topics is not encyclopedic and the material on transcendental functions and on parametric equations is woven throughout the book instead of being treated in separate capacity.
● Calculus: Early on Vectors introduces vectors and vector functions in the first semester and integrates them throughout the volume. It is suitable for students taking engineering and physics courses meantime with calculus.
● Brief Applied Calculus is intended for students in business, the social sciences, and the life sciences.
● Biocalculus: Calculus for the Life Sciences is intended to bear witness students in the life sciences how calculus relates to biology.
● Biocalculus: Calculus, Probability, and Statistics for the Life Sciences contains all the content of Biocalculus: Calculus for the Life Sciences too as three additional chapters covering probability and statistics.
The changes accept resulted from talking with my colleagues and students at the University of Toronto and from reading journals, every bit well as suggestions from users and reviewers. Here are some of the many improvements that I've incorporated into this edition:
● The information in examples and exercises have been updated to exist more timely.
● New examples take been added (see Examples 5.1.5, 11.2.5, and fourteen.3.3, for instance). And the solutions to some of the existing examples accept been amplified.
● 3 new projects take been added: The project Planes and Birds: Minimizing Energy (page 271) asks how birds can minimize power and free energy by flapping their wings versus gliding. The projection Controlling Red Blood Prison cell Loss During Surgery (page 473) describes the ANH process, in which blood is extracted from the patient before an operation and is replaced by saline solution. This dilutes the
patient's blood so that fewer red claret cells are lost during haemorrhage and the extracted claret is returned to the patient later surgery. In the project The Speedo LZR Racer (page 976) it is explained that this suit reduces drag in the h2o and, equally a result, many swimming records were broken. Students are asked why a small-scale decrease in drag can take a large effect on functioning.
● I have streamlined Chapter fifteen (Multiple Integrals) by combining the first 2 sections then that iterated integrals are treated before.
● More than 20% of the exercises in each affiliate are new. Here are some of my favorites: 2.ane.61, two.2.34–36, iii.3.30, 3.3.54, 3.7.39, 3.vii.67, 4.1.xix–20, 4.two.67–68, four.4.63, five.i.51, 6.2.79, six.7.54, 6.viii.ninety, eight.1.39, 12.5.81, 12.6.29–30, 14.six.65–66.
In add-on, there are some expert new Bug Plus. (Encounter Problems 10–12 on folio 201, Problem ten on page 290, Problems 14–fifteen on pages 353–54, and Problem 8 on folio 1026.) May not be copied, scanned, or duplicated, in whole or in part. Due to electronic rights, some third political party content may exist suppressed from the eBook and/or eChapter(s). Editorial review has deemed that whatever suppressed content does not materially bear upon the overall learningexperience. Cengage Learning reserves the right to remove additional content at whatsoever time if subsequent rights restrictions require it.
Conceptual Exercises
The virtually of import fashion to foster conceptual understanding is through the issues that we assign. To that end I have devised diverse types of problems. Some practise sets begin with requests to explain the meanings of the basic concepts of the section. (Run across, for case, the first few exercises in Sections 1.5, 1.8, eleven.ii, 14.ii, and 14.3.) Similarly, all the review sections begin with a Concept Check and a True-False Quiz. Other exercises test conceptual understanding through graphs or tables (run across Exercises ii.1.17, 2.ii.33–36, 2.2.45–50, 9.1.11–xiii, 10.1.24–27, 11.10.2, xiii.2.one–two, 13.3.33–39, 14.i.1–2, 14.1.32–38, fourteen.1.41–44, xiv.3.3–10, 14.6.1–ii, 14.7.iii–4, 15.1.6–8, 16.ane.eleven–18, 16.2.17–18, and 16.3.1–2). Another type of exercise uses verbal description to test conceptual understanding (come across Exercises 1.viii.10, 2.two.64, 3.3.57–58, and 7.8.67). I particularly value bug that combine and compare graphical, numerical, and algebraic approaches (see Exercises 2.7.25, 3.4.33–34, and ix.4.4).
Graded Practise Sets
Each exercise prepare is carefully graded, progressing from basic conceptual exercises and skill-evolution problems to more challenging issues involving applications and proofs.
Real-Globe Data
My assistants and I spent a great deal of time looking in libraries, contacting companies and government agencies, and searching the Cyberspace for interesting real-earth data to introduce, motivate, and illustrate the concepts of calculus. Every bit a effect, many of the examples and exercises deal with functions defined past such numerical data or graphs. Run into, for example, Figure 1 in Section 1.1 (seismograms from the Northridge earthquake), Do ii.2.33 (unemployment rates), Exercise 4.1.sixteen (velocity of the space shuttle Endeavor), and Effigy 4 in Department four.4 (San Francisco power consumption). Functions of two variables are illustrated by a table of values of the wind-chill alphabetize as a function of air temperature and wind speed (Example xiv.ane.ii). Partial derivatives are introduced in Department 14.3 by examining a column in a tabular array of values of the heat index (perceived air temperature) as a function of the actual temperature and the relative humidity. This example is pursued further in connection with linear approximations (Example 14.4.iii). Directional derivatives are introduced in Section fourteen.6 past using a temperature contour map to approximate the rate of change of temperature at Reno in the management of Las Vegas. Double integrals are used to estimate the average snowfall in Colorado on December 20–21, 2006 (Example xv.one.9). Vector fields are introduced in Department 16.1 by depictions of bodily velocity vector fields showing San Francisco Bay wind patterns.
Projects
One style of involving students and making them agile learners is to have them piece of work (possibly in groups) on extended projects that give a feeling of substantial achievement when completed. I have included 4 kinds of projects: Applied Projects involve applications that are designed to appeal to the imagination of students. The project after Section 9.3 asks whether a ball thrown upward takes longer to reach its maximum height or to fall back to its original superlative. (The reply might surprise y'all.) The project after Section 14.8 uses Lagrange multipliers to determine the masses of the three stages of a rocket so as to minimize the total mass while enabling the rocket to reach a desired May not be copied, scanned, or duplicated, in whole or in part.

velocity. Laboratory Projects involve technology; the 1 post-obit Department 10.ii shows how to utilise Bézier curves to design shapes that represent messages for a laser printer. Writing Projects ask students to compare present-day methods with those of the founders of calculus—Fermat's method for finding tangents, for instance. Suggested references are supplied. Discovery Projects anticipate results to exist discussed after or encourage discovery through pattern recognition (run into the ane following Section vii.six). Others explore aspects of geometry: tetrahedra (after Department 12.iv), hyperspheres (after Section 15.6), and intersections of 3 cylinders (subsequently Department xv.7). Boosted projects can be found in the Teacher'due south Guide (meet, for instance, Group Practice four.1: Position from Samples).
Problem Solving
Students usually have difficulties with problems for which at that place is no single well-defined process for obtaining the answer. I think nobody has improved very much on George Polya's 4-stage problem-solving strategy and, accordingly, I accept included a version of his problem-solving principles following Chapter 1. They are applied, both explicitly and implicitly, throughout the volume. After the other chapters I have placed sections called Problems Plus, which feature examples of how to tackle challenging calculus issues. In selecting the varied issues for these sections I kept in heed the following communication from David Hilbert: "A mathematical problem should exist difficult in order to entice u.s.a., notwithstanding not inaccessible lest it mock our efforts." When I put these challenging issues on assignments and tests I grade them in a different way. Here I reward a educatee significantly for ideas toward a solution and for recognizing which problem-solving principles are relevant.
Dual Treatment of Exponential and Logarithmic Functions
There are two possible means of treating the exponential and logarithmic functions and each method has its passionate advocates. Because ane often finds advocates of both approaches teaching the aforementioned course, I include full treatments of both methods. In Sections half dozen.2, half dozen.3, and 6.four the exponential function is defined kickoff, followed by the logarithmic function as its inverse. (Students accept seen these functions introduced this way since high school.) In the alternative approach, presented in Sections 6.two*, 6.iii*, and 6.4*, the logarithm is defined every bit an integral and the exponential office is its inverse. This latter method is, of course, less intuitive but more elegant. You can apply whichever treatment you adopt.
If the first approach is taken, then much of Affiliate 6 tin be covered before Capacity 4 and 5, if desired. To adapt this selection of presentation there are specially identified bug involving integrals of exponential and logarithmic functions at the cease of the appropriate sections of Capacity 4 and 5. This gild of presentation allows a faster-paced form to teach the transcendental functions and the definite integral in the first semester of the course.
For instructors who would like to go fifty-fifty farther in this direction I accept prepared an alternate edition of this volume, called Calculus: Early on Transcendentals, Eighth Edition, in which the exponential and logarithmic functions are introduced in the first chapter. Their limits and derivatives are constitute in the second and third chapters at the aforementioned time as polynomials and the other elementary functions.
Tools for Enriching Calculus
Editorial review has accounted that whatever suppressed content does not materially impact the overall learning experience. Cengage Learning reserves the correct to remove additional content at any time if subsequent rights restrictions require it.approach. In sections of the book where technology is particularly appropriate, marginal icons straight students to TEC Modules that provide a laboratory environment in which
they can explore the topic in unlike ways and at dissimilar levels. Visuals are animations of figures in text; Modules are more elaborate activities and include exercises.
Instructors can choose to become involved at several different levels, ranging from simply encouraging students to use the Visuals and
Modules for independent exploration, to assigning specific exercises from those included with each Module, or to creating additional exercises, labs, and projects that make use of the Visuals and Modules.
TEC also includes Homework Hints for representative exercises (usually odd-numbered) in every department of the text, indicated past press the exercise number in red.
These hints are normally presented in the form of questions and try to imitate an effective teaching assistant past functioning as a silent tutor. They are constructed so as not to reveal any more than of the bodily solution than is minimally necessary to make further progress. Enhanced WebAssign
Technology is having an touch on the style homework is assigned to students, particularly in big classes. The use of online homework is growing and its appeal depends on ease of use, grading precision, and reliability. With the Eighth Edition nosotros accept been working with the calculus community and WebAssign to develop an online homework system. Upwardly to 70% of the exercises in each department are assignable as online homework, including free response, multiple option, and multi-part formats.
The system also includes Active Examples, in which students are guided in step-bystep tutorials through text examples, with links to the textbook and to video solutions
