Example: Calculating the inverse of a given matrix Question:Consider the following matrix: \[A = \begin{bmatrix} \displaystyle 1&\displaystyle 2&\displaystyle 1\\[0.6em]\displaystyle 2&\displaystyle 1&\displaystyle 4\\[0.6em]\displaystyle 1&\displaystyle 1&\displaystyle 1 \end{bmatrix} \]...
Learn some different ways to tell if a matrix is invertible. For instance, a square matrix is invertible if and only if its determinant is nonzero. You can also tell by checking if the matrix is equivalent (under row operations) to a diagonal matrix with
Let A and B be n x n matrices such that AB is invertible. Prove that A and B are invertible. Give an example to show that arbitrary matrices A and B need not be invertible if AB is invertible. Show how to use eigenvalues to determine if a matrix is invertible. ...

Using ideas of Suslin-Vasertein we prove some results concerning completing a unimodular row to an invertible matrix. For example, if A is a polynomial ring over a field in any number of indeterminates, then any unimodular row over A of length m n + 2 in which appears a polynomial in ...
