Elementary Linear Algebra: A First Course in Pure and Applied Math

This innovative book features an "Active Reading" theme, stressing the learning of proofs by first focusing on reading mathematics. This helps users understand that linear algebra is not just another course in computation. A secondary theme on Least Squares and the "best" solution to Ax = b adds a modern computational flavor that readers will welcome. Key ideas are revisited & reinforced throughout—Linear independence/dependence; eigenvalues/vectors; projection of one vector on another; the plane spanned by vectors.
