matix is lower triangular, and the inverse of an invertible upper triangular matrix is upper triangular. Note, Give proves of the above theorem and two examples for each part. 1example should be of order2×2and other would be of3...
The eigenvalues of an upper (lower) triangular matrix are the elements on the main diagonal of the matrix. ► The product of all the eigenvalues of a matrix (counting multiplicity) equals the determinant of the matrix. ► A matrix is singular if and only if it has a zero eigenvalue....
Show that if A is an invertible upper triangular matrix, then A^-1 is also an upper triangular matrix Homework Equations The Attempt at a Solution The inverse of something just flips the main diagonal and leaves everything else where is was just changing the signs. How do I say this in ...
