Inverse of a 2x2 Matrix

Описание к видео Inverse of a 2x2 Matrix

This precalculus video tutorial explains how to determine the inverse of a 2x2 matrix. It provides a simple formula to determine the multiplicative inverse of a matrix. You can check to see if you have the right answer by multiplying the matrix and its inverse to see if you get the multiplicative identity matrix I2. This video contains plenty of examples and practice problems.
