Noncommutativity of matrix product. Determinants of 2 x 2 and 3 x 3 matrices. Determinant of a product. Effect of elementary row operations on determinants. Determinants as areas and volumes. Matrix inverses, in particular 2 x 2 inverses. Overview of vectors in 1, 2 and 3 dimensions. Position and displacement vectors. Triangle and parallelogram laws. Vector arithmetic, norm, distance, dot product and angle, orthogonal projection. The triangle and Cauchy-Schwartz inequalities. The cross product and triple product in 3-dimensions. The normal vector of a plane and the vector equation of a line. Complex numbers and the plane. Other topics, such as the eigenvalues of 2 x 2 matrices, roots of unity, geometric problems, quadratic forms, linear maps via 2 x 2 matrices.
