Give an example of two non-zero 2xx2 matrices A and B such that AB=O .

Give an example of two non-zero 2xx2 matrices A and B such that A B=O .

Give an example of two non-zero 2xx2 matrices A and B such that A B=O .

Give an example of a 2xx2 (non-zero) matrix A,B,C such that

Write two non-zero matrices A and B for which AB=0 .

Give an example to show that the product of two non-zero matrices is a zero matrix.

If A and Bare two non-zero square matrices of the same order, such that AB=0, then (a) at least one of A and B is singular (b) both A and B are singular (c) both A and B are non-singular (a) none of these

A and B are two non-zero square matrices such that AB = O . Then,

If A and B are non-zero square matrices of same order such that AB=A and BA=B then prove that A^(2)=A and B^(2)=B

Suppose a and b are two non-zero vectors and angle between a and b is theta, " where "0 lt theta lt pi//2 . If abs(a times b)=abs(a*b)," then "pi//theta= _______
