Title overview
For courses in introductory technical math.
The student-friendly, acclaimed best seller in technical math
Basic Technical Mathematics continues Washington's highly regarded approach with updates that support student understanding of mathematical techniques and how they apply on the job. Its concise narrative focuses on the essentials students need, with no added theory or digressions. Intended primarily for students in technical or pre-engineering programs, it uses a vast number of applications to create a solid foundation in mathematics and demonstrate its applicability in various technical fields. The 12th Edition updates applications and data throughout for increased relevancy.
Hallmark features of this title
- Technical applications (over 2000 application exercises and 300 applied examples) are drawn from fields such as aeronautics, construction, environmental, and more. Many involve modern technologies like solar energy and fiber optics.
- Solved examples feature blue "help text" to explain each step of the solution.
- Problem sets offer exercises spanning practice and writing exercises to applications and practice tests.
- "Caution" and "Note" features point out common errors, topics that frequently challenge students, and key material.
- Practice Exercises after key examples are provided, with answers at the end of the exercise set for the section.
- The online Graphing Calculator Handbook is referenced throughout the text via short URLs (or direct links in the eText) that take students directly to the relevant content.
New and updated features of this title
- Real-world data and scenarios are updated throughout the text to maintain currency and relevancy for students. For example, see the updated data on social media usage in section 22.1, Graphical Displays of Data.
- A new Appendix E covers binary and hexadecimal numbers. This appendix is available online at bit.ly/3h1t3lt and has been added at users' requests.
Key features
Features of MyLab Math for the 12th Edition
- Approximately 220 new assignable, algorithmic exercises have been added to the course. MyLab exercises reflect the approach and learning style of the text with learning aids that include guided solutions, videos, and sample problems. About 175 of the new exercises are based on existing textbook exercises; the remainder are new applications written by the author.
- Existing MyLab exercises have been revised to improve clarity.
- Significantly increased video coverage includes 165 new example videos for a total of 600 instructional videos, many with author Rich Evans. All videos are now re-correlated to the exercises in MyLab; when a student chooses "Video" as a learning aid within a MyLab exercise, they can be sure that the video will be helpful.
- A new Guide to Video-Based Assignments helps instructors create assignments containing video by showing which MyLab questions relate to each video.
- The online Graphing Calculator Handbook is referenced throughout the text via short URLs (or direct links in the eText) that take students directly to the relevant content.
