WebApr 7, 2024 · An invertible matrix is a matrix that has an inverse. In this video, we investigate the relationship between a matrix's determinant, and whether that matrix is invertible. Created by ... WebSep 17, 2024 · Definition 3.1.1. An n × n matrix A is called invertible if there is a matrix B such that BA = In, where In is the n × n identity matrix. The matrix B is called the inverse of A and denoted A − 1. since A rotates vectors in R2 by 90 ∘ and B rotates vectors by − 90 ∘. It's easy to check that.
