Calculus & Its Applications, 14th Edition

Personalize learning with MyLab Math

MyLab™ Math is an online homework, tutorial, and assessment program designed to work with this text to engage students and improve results. Within its structured environment, students practice what they learn, test their understanding, and pursue a personalized study plan that helps them absorb course material and understand difficult concepts.

NOTE: This text requires a title-specific MyLab Math access kit. The title-specific access kit provides access to the Goldstein et al., Calculus & Its Applications 14/e accompanying MyLab course ONLY.

• Many improvements have been made to the overall functionality of MyLab Math since the previous edition. However, beyond that, we have also increased and improved the content specific to this text.
• Setup & Solve exercises require students to first describe how they will set up and approach the problem. This reinforces conceptual understanding of the process applied in approaching the problem, promotes long term retention of the skill and mirrors what students will be expected to do on a test.
• Conceptual Question Library exercises provide additional conceptual, application-focused questions for instructors to use on homework or assessments.
• MathTalk videos connect the math to the real world (particularly business). The videos include assignable exercises to gauge students’ understanding of video content.
• Interactive Figures illustrate key concepts and allow manipulation for use as teaching and learning tools. These are now in HTML format (no plug-in required) and are supported by assignable exercises and tutorial videos.
• Over 275 Example-based videos, 97 of which are new to this edition, are available as learning aids within exercises and for self-study. The Guide to Video-Based Assignments makes it easy to assign videos for homework by showing which MyLab Math exercises correspond to each video.
• Skills for Success Modules help students with the life skills that can make the difference between passing and failing.
• An Integrated Review MyLab Math course contains pre-made quizzes to assess the prerequisite skills needed for each chapter, plus personalized remediation for any gaps in skills that are identified.
• Graphing Calculator and Excel Spreadsheet Manuals, specific to this course, are now downloadable from MyLab Math.
• Instructor’s Answers document (downloadable from MyLab Math)  provides all answers in one place and augments the downloadable Instructor’s Solutions Manual, which contains all solutions.

New to the Book

• More intuitive organization and explanation within examples makes properties and theorems easier to follow and recall.
• 225 new exercises and 30 worked examples have been added, bringing the total to 4,200 exercises and 520 examples.
• “Help text” within examples (shown in blue type) helps students understand key algebraic and numerical transitions.
• “For Review” side margin features remind students of a concept that is needed and direct them back to the section in which it was covered earlier in the text.
• Graphing calculator screens have been updated to the TI-84 Plus CE format and are now in color.
• All 3-dimensional figures in the text have been re-rendered using the latest software. The authors took full advantage of the capabilities of the rendering software to make the figures more effective pedagogically.
• In cases where properties or theorems that were formerly numbered (e.g., Property 4) have a commonly used name (e.g., Power of a Quotient Rule), the authors used the name rather than the number. This allows for more intuitive explanations within examples and is better aligned to how concepts are explained in class.

• Moved the material on the properties and graphs of exponential functions from 4.3 to 4.2.
• Replaced Examples 1, 2, and 3 from 4.3 with new examples that better build on the properties of derivatives introduced earlier. Example 3 introduces a new concept of combined returns to illustrate applications of linear combinations of exponential functions.
• Moved the material on differential equations in 4.3 to Chapter 5.

• Used investment portfolios to illustrate applications involving solutions of equations with logarithms in Example 4 in 4.4.
• Rewrote the introduction of 4.5 to better display properties of the natural logarithm and its derivative.
• Added a new example on differentiation of the natural logarithm in 4.5.
• Modified and added over twenty exercises in 4.5.
