Linear Algebra For Dummies

Linear Algebra For Dummies serves as an easy-to-follow guide that introduces (or re-introduces) readers to key concepts such as matrices, vector spaces, and eigenvalues and eigenvectors. It presents the information in a way that allows readers to fully digest not just the "how" of solving linear algebraic problems, but also the "why.

Learn to:



Solve linear algebra equations in several ways
Put data in order with matrices
Determine values with determinants
Work with eigenvalues and eigenvectors

Your hands-on guide to real-world applications of linear algebra

Does linear algebra leave you feeling lost? No worries —this easy-to-follow guide explains the how and the why of solving linear algebra problems in plain English. From matrices to vector spaces to linear transformations, you'll understand the key concepts and see how they relate to everything from genetics to nutrition to spotted owl extinction.



Line up the basics — discover several different approaches to organizing numbers and equations, and solve systems of equations algebraically or with matrices
Relate vectors and linear transformations — link vectors and matrices with linear combinations and seek solutions of homogeneous systems
Evaluate determinants — see how to perform the determinant function on different sizes of matrices and take advantage of Cramer's rule
Hone your skills with vector spaces — determine the properties of vector spaces and their subspaces and see linear transformation in action
Tackle eigenvalues and eigenvectors — define and solve for eigenvalues and eigenvectors and understand how they interact with specific matrices
