If `P={p,q,r,s,t,u} and Q capR={q,r,v,w}`, find
`(P-Q)cup(P-R)`

If P={p,q,r,s,t,u} and Q capR={q,r,v,w} , find (P cup Q) cap(PcupR)

If A={p,q,r,s}, B={r,s,t,u} and C={p,q,r}, then (A-B)-C is .........

Consider the following relations from A to B where A={u, v, w, x, y, z} and B={p, q, r, s}. 1. {(u,p),(v,p),(w,p),(x,q),(y,q),(z,q)} 2. {(u,p),(v,q),(w,r),(z,s)} 3. {(u,s),(v,r),(w,q),(u,p),(v,p),(z,q)} 4. {(u,q),(v,p),(w,s),(x,r),(y,q),(z,s)} Which of the above relations are not functions ?

If P-Q-R and if d(P,R)=10 , d(Q,R)=3 , then find d(P,Q) .

if P,q, r, s in R such that p r= 2 ( q+ s) then

p,q,q,r Show that ,q,p,,q,r,r,p,r,q

IF P-Q-R and if d(P,R)=10, d(Q,R)=3, then find d(P,Q).

Show that for all values of p, q, r, s the matrices, P=[(p,q),(-q,p)] , and Q=[(r,s),(-s,r)], PQ=QP.

If A = |{:(p,q,r),(r,p,q),(q,r,p):}|and A A ^(T) = I "then" p^(3) + q^(3) + r^(3) =
