- Identify the inverse of the matrix
- Determine that if the determinant of a matrix is 0, then the matrix does not have an inverse
- Identity matrix
About the Lesson
This lesson involves modifying a 2 X 2 matrix being multiplied by another 2 X 2 matrix until their product is the identity matrix. As a result, students will:
- Test their newly learned knowledge and determine the inverse of any 2 X 2 matrix.
- Determine that, if the determinant of a matrix is 0, then the matrix does not have an inverse.
