10.1 Notation

A new and interactive introduction to linear algebra and matrix theory

Linear Algebra focuses on computation as a tool to build comprehension of this subject’s key principles. Definition-based topics are introduced to connect new concepts as the book progresses. A focus approach is taken on the foundational ideas of linear algebra. This book includes:

  • 350+ auto-graded participation activities intended as reading exercises, such as question sets and animations
  • Adopters have access to a test bank with questions for every chapter
  • 250+ 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
This zyBook replaces a traditional textbook. The modular approach taken by the authors allows instructors to fully customize by rearranging sections or including sections from other zyBooks, such as Algebra, Discrete Math, and Calculus.

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

“The most striking aspect of zyBooks for me as an instructor has been the ability to introduce a topic and then point my students to specific exercises/activities in zyBooks that would not only expound on the concept but allow them to practice them with confidence.”
