Inverse Matrix Teacher Resources

A video lesson that works through a concrete example to find the inverse of a 3 x 3 matrix. The original matrix is augmented by the identity matrix and then put in reduced row echelon form. The result of the row operations on the...

A video lesson proving that the product of a matrix and its transpose is invertible if all of the columns of the originial matrix are linearly independent. [12:34]

The resource is a lesson guide that teaches the basic mathematical concepts needed for teaching economics and financial economics. Topics include matrix transposition, matrix inversion, and operations with matrices. Applications of Excel...

A video lesson that gives an in-depth, algebraic proof showing that the inverse of a linear transformation is also linear. [21:25]

Inverse matrices are very useful for solving matrix equations. But, given a matrix, how do you invert it? How do you find the inverse? The technique for inverting matrices is kind of clever. For a given matrix A and its inverse A-1, we...
