If `A` is a square matrix such that `a_(ij)=(i+j)(i-j),` then for `A` to be non-singular the order of the matrix can be .

If A is a square matrix for which a_(ij)=i^(2)-j^(2) , then matrix A is

If A=[a_(ij)] is a 2xx2 matrix such that a_(ij)=i+2j, write A

If A=[a_(ij)] is a square matrix of even order such that a_(ij)=i^(2)-j^(2), then

If A=[a_(ij)] is a square matrix such that a_(ij)=i^(2)-j^(2), then write whether A is symmetric or skew-symmetric.

If A is a n n matrix such that a_(ij)=sin^(-1)sin(i-j)AA i,j then which of the following statement is not true

If A=[a_(ij)] is a square matrix of even order such that a_(ij)=i^(2)-j^(2), then A is a skew- symmetric matrix and |A|=0 (b) A is symmetric matrix and |A| is a square (c) A is symmetric matrix and |A|=0 (d) none of these

The element a_(ij) of square matrix is given by a_(ij)=(i+j)(i-j) then matrix A must be

Let A=[a_(ij)] be a square matrix of order n such that {:a_(ij)={(0," if i ne j),(i,if i=j):} Statement -2 : The inverse of A is the matrix B=[b_(ij)] such that {:b_(ij)={(0," if i ne j),(1/i,if i=j):} Statement -2 : The inverse of a diagonal matrix is a scalar matrix.

In square matrix A=(a_(ij)) if i lt j and a_(ij)=0 then A is

A square matrix [a_(ij)] such that a_(ij)=0 for i ne j and a_(ij) = k where k is a constant for i = j is called :
