Properties of Matrix Arithmetic We will take a more in depth look at many of the properties of matrix arithmetic and the transpose.

Inverse Matrices and Elementary Matrices Here we’ll define the inverse and take a look at some of its properties. We’ll also introduce the idea of Elementary Matrices.

Finding Inverse Matrices In this section we’ll develop a method for finding inverse matrices.

Special Matrices We will introduce Diagonal, Triangular and Symmetric matrices in this section.

LU-Decompositions In this section we’ll introduce the LU-Decomposition a way of “factoring” certain kinds of matrices.

Systems Revisited Here we will revisit solving systems of equations. We will take a look at how inverse matrices and LU-Decompositions can help with the solution process. We’ll also take a look at a couple of other ideas in the solution of systems of equations.

Determinants

The Determinant Function We will give the formal definition of the determinant in this section. We’ll also give formulas for computing determinants of and matrices.

Properties of Determinants Here we will take a look at quite a few properties of the determinant function. Included are formulas for determinants of triangular matrices.

Using Row Reduction to Find Determinants Here we will take a look at the second method for computing determinants in general.

Cramer’s Rule We will take a look at yet another method for solving systems. This method will involve the use of determinants.

Euclidean n-space

Vectors In this section we’ll introduce vectors in 2-space and 3-space as well as some of the important ideas about them.

Dot Product & Cross Product Here we’ll look at the dot product and the cross product, two important products for vectors. We’ll also take a look at an application of the dot product.

Euclidean n-Space We’ll introduce the idea of Euclidean n-space in this section and extend many of the ideas of the previous two sections.
