What is a 3 x 3 matrix? A matrix is a two-dimensional array of numbers (which can be real or complex), arranged in columns and rows. A 3x3 matrix has three columns and three rows, and therefore, 9 entries. What is the determinant formula?
As mentioned, before we can find the determinant of a matrix, we need to have a square matrix. That is, the matrix must be of order 2 x 2, or 3 x 3, or 4 x 4, or n x n in general. The key formula for finding the determinant of a matrix is ad - bc. This formula applies...
In a 4 x 4 matrix, the minors are determinants of 3 X 3 matrices, and ann x nmatrix has minors that are determinants of(n - 1) X (n - 1)matrices. To find the determinant of a 3 X 3 or larger matrix, first choose any row or column. Then the minor of each element in that ...

of real vectors, we make obvious changes: we are no longer in the Cartesian plane, but in three-dimensional space; the matrix used to perform linear transformations is a matrix; the determinant is the scaling factor that allows us to compute the volumes of the linearly transformed regions. ...
