Find the Identity relation,when. A.={a,b,c,d}

If A = {1,2,3,4} and I_A be the identity relation on A, then

If A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying the equation A A^T=9I , where I is 3xx3 identity matrix, then the ordered pair (a,b) is equal to : (A) (2,-1) (B) (-2,1) (C) (2, 1) (D) (-2,-1)

If for a matrix A,A^2+I=0, where I is an identity matrix then A equals (A) [(1,0),(0,1)] (B) [(-1,0),(0,-1)] (C) [(1,2),(-1,1)] (D) [(-i,0),(0,-i)]

If A = {1,2,3,…,9} and R is the relation in A xx A defined by (a, b) R (c, d), if a+d=b+c for (a, b), (c, d) in A xx A . Prove that R is an equivalence relation.

If A={a,b,c,d}, then on A . (i) write the identity relation I_(A) . (ii) write a reflexive relation which is not the identity relation.

If A={a,b,c,d}, then on A . (i) write the identity relation I_(A) . (ii) write a reflexive relation which is not the identity relation.

If A={1,2,3,4,} and I_(A) be the identity relation on A, then _______

Let A={1,2,3},\ B={a , b , c , d} be two sets and let R={(1, a),\ (1, c),\ (2, d),(2, c)} be a relation from A to B. Then R^(-1)={(a ,1),\ (c ,1),\ (d ,2),\ (c ,2)} is a relation from B to A.
