A new and interactive introduction to linear algebra and matrix theory
Linear Algebra uses an interactive approach to build comprehension of this subject’s foundational ideas. Definition-based topics are introduced to connect new concepts as the book progresses. This book includes:
- New block proof tool that helps students learn how formal math proofs are written
- 350+ auto-graded participation activities intended as reading exercises, such as question sets and animations
- 300+ end-of-section exercises for practice or homework
- Homework-appropriate, auto-graded, and randomized challenge activities in every section
- Dozens of applications connect key concepts in linear algebra to real-world examples in physics, chemistry, circuits, and more
- Adopters have access to a test bank with over 200 questions
Example of proof from Linear Algebra:
What is a zyBook?
Linear Algebra is a web-native, interactive zyBook that helps students visualize concepts to learn faster and more effectively than with a traditional textbook. (Check out our research.)
Since 2012, over 1,700 academic institutions have adopted digital zyBooks to transform their STEM education.
zyBooks benefit both students and instructors:
- Instructor benefits
- Customize your course by reorganizing existing content, or adding your own content
- Continuous publication model updates your course with the latest content and technologies
- Robust reporting gives you insight into students’ progress, reading and participation
- Save time with auto-graded labs and challenge activities that seamlessly integrate with your LMS gradebook
- Build quizzes and exams with hundreds of included test questions
- Student benefits
- Learning questions and other content serve as an interactive form of reading
- Instant feedback on labs and homework
- Concepts come to life through extensive animations embedded into the interactive content
- Review learning content before exams with different questions and challenge activities
- Save chapters as PDFs to reference the material at any time
