Determinants of Triangular Matrices | Linear Algebra
We discuss how to find the determinant of triangular matrices of any size. This includes determinants of upper triangular matrices, determinants of lower triangular matrices, and determinants of diagonal matrices. We see through a generalized example of the cofactor expansion that to calculate the determinant of a triangular matrix, we need only multiply the entries in the main diagonal. #linearalgebra
