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

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

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

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

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

Construct the matrix A = [a_(ij)]_(3xx3), where a_(ij)=i-j . State whether A is symmetric or skew- symmetric.

Construct the matrix A=[a_(ij)]_(3xx3) where a_(ij)=i-j . State whether A is symmetric or skew symmetric.
