The zyBooks Approach
Less text doesn’t mean less learning.
An exceptionally interactive introduction to linear algebra and matrix theory. This zyBook provides a solid introduction to linear algebra with a focus on computation as a tool to develop the intuition necessary to understand and prove the subject’s main ideas. Numerous animations help the learner visualize key concepts. Since many real-world phenomena can be modeled using linear equations, select applications from physics, chemistry, engineering, and social sciences are introduced to reinforce conceptual understanding of the material. Learning questions engage students and walk them through concepts incrementally. Explanations are given for both correct and incorrect answers, which break down common misconceptions and further enable learning. End-of-section exercises provide students the opportunity to practice techniques introduced in the text and prove additional properties and theorems.
This zyBook replaces a traditional textbook. The modular approach taken by the authors allows instructors to rearrange or combine sections with other zyBooks, such as Algebra, Discrete Math, and Calculus.
