Let S be the set of 2xx2 matrices given by S={A=[[a,b],[c,d]],"where" a,b,c,d,in I} , such that A^(T)=A^(-1) Then

Let S be the set of 2xx2 matrices given by S={A=[[a,b],[c,d]],"where" a,b,c,d,in I} , such that A^(T)=A^(-1) Then

(a)If A=[a,b],B=[c,d],C=[d,e] then {(a,c),(a,d),(a,e),(b,c),(b,d),(b,e)}=………

If A={a,b,c,d},B={p,q,r,s} than which of the following are relations from A rarr B? Give reasons for your answer: R_(2)={(qdot b),(c,s),(d,r)}
