Consider the following two sets. X = { x sin ( x ) = 0 where x has units of radians } X={xsin(x)=0 where x has units of radians} Y = { y sin ( y ) = 0 where y has units of radians } Y={ysin(y)=0 where y has units of radians} 1. Indicate whether each of X X and Y Y is a proper subset of each of R R, Q Q, and Z Z. You should have six relational statements in total, each using either or . 2. Give a description for X Y XY using set builder notation. Do not use sin sin or any other functions in the description. 3. Give a description for Y X YX using set builder notation. Do not use sin sin or any other functions in the description. 4. Give a description for X Y XY using set builder notation. Do not use sin sin or any other functions in the description
