Inverse Adjoint and Determinant Method

Additional Resources:

In this lesson, we will learn a shortcut that allows us to find the inverse of a nonsingular square matrix. This method involves using determinants and the adjoint (adjugate). To use this process, we will state a formula that tells us that the inverse of an invertible square matrix can be found by multiplying 1/det times the adjoint (adjugate) of the matrix.
