Find the value of a and b, given that `P |\| q` and `r |/| s`.

Find the value of a and b, given that p || q and r || s.

For three vectors p, q and r, if r = 3p + 4q and 2r = p - 3q, then

Let P, Q, R and S be statement and suppose that P rarr Q rarr R rarr P . If ~S rarr R , then

If p^(th), q^(th), r^(th) and s^(th) terms of an A.P. are in G.P, then show that (p – q), (q – r), (r – s) are also in G.P.

If P={a,b,c} and Q={r}, form the sets P xx Q and Q xx P .

If the points P(-3,9) ,Q(a , b) and R(4 , - 5) are collinear and a + b=1, then find the values of a and b.
