Let A= `[a_(ij)]_(nxxn)` where `a_(ij) = i^2-j^2.` Then A is: (A) skew symmetric matrix (B) symmetric matrix (C) null matrix (D) unit matrix

Let A=[a_(ij)] is a square matrix of order 2 where a_(ij)=i^(2)-j^(2) . Then A is (i) Skew - symmetric matrix (ii) Symmetric matrix (iii) Diagonal matrix (iv) None of these

[(2,3),(3,4)] is a a)Symmetric matrix b)Skew-symmetric matrix c)null matrix d)identity matrix

A 2xx2 matrix A = [a_(ij)] , where a_(ij) = (i+j)^2 is

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

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=[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

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