Determinant of a 1x3 matrix
WebThe area of the little box starts as 1 1. If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things in, then its determinant is less than 1 1. WebUsing minors we demonstrate one way to compute the determinant of a 3 × 3 matrix. The technique is called expansion by cofactors. Let Abe any 3×3 matrix: A= a 11 a 12 a 13 a …
