True or False
If `P = {1,2}, `then `PxxPxxP = {(1,1,1),(2,2,2),(1,2,2),(2,1,1)}`

Let A = (1,2,3) and R = (1,1), (2,2), (1,2), (2,1), (1,3) then R is

Show that the points (1,1,1),(2,-1,2),(-1,2,2) and (2,2,-1) are coplanar.

Let A =[[1,2,2],[2,1,2],[2,2,1]] , then

State True/ False: This is 1/2

Given set A = {1,2,3}, then the relation : R = {(1,1),(2,2),(3,3)} is reflexive. (True/False)

Which option is true about these points (1,1),(2,2),(-2,-2)

If overline(P_1P_2) is perpendicular to overline(P_2P_3) , then the value of k is, where P_1(k, 1, -1), P_2(2k, 0, 2) and P_3(2+2k, k, 1) is …..

Evaluate the following {:[(1,-1),(0,2),(2,3)] ([(1,0,2),(2,0,1)] - [(0,1,2),(1,0,2)])

If A = {:[(1,2,3),(-1,0,2),(1,-8,-1)], B = [(4,5,6),(-1,0,1),(2,1,2)], C = [(-1,-2,1),(-1,2,3),(-1,-2,2)] find A - 2B + 3C
