show that the product of two triangular matrices is itself triangular
Sum of two skew-symmetric matrices is always ......... Matrix.
Matrices A and B will be inverse of each other only if
A is a matric of order 3 xx 3 . If A'=A and five entries in the matrix are of the kind are remaining four are of another king. Then the maximum number of such matrices is greater then or equal to
Let A,B and C be nxxn matrices. Which one of the following is a correct statement?
Which of the following matrices is equal to 4[(-1,2),(0,-4)] ?
Let A be the set of all 3xx3 skew-symmetri matrices whose entries are either -1,0,or1. If there are exactly three 0s three 1s, and there (-1)' s , then the number of such matrices is __________.
