WebYou found an nxn matrix with determinant 0, and so the theorem guarantees that this matrix is not invertible. What "the following are equivalent" means, is that each condition (1), (2), and (3) mathematically mean the same thing. It is not saying that every nxn matrix has a nonzero determinant. WebSep 16, 2024 · Outcomes. Use determinants to determine whether a matrix has an inverse, and evaluate the inverse using cofactors. Apply Cramer’s Rule to solve a \(2\times 2\) or a \(3\times 3\) linear system.; Given data points, find an appropriate interpolating polynomial and use it to estimate points.
