Given the set a = {(x, y) / / X / + / Y / ≤ 1} B = {x, y) / X & # 178; + Y & # 178; ≤ 1}, what is the relationship between a and B
Set a is contained in set B
Set a represents a square area with a side length of √ 2, the center of which is at the origin, and the coordinate axis is its diagonal
Set B represents a circle whose center is at the origin and radius is 1
The combination of number and shape shows that set a is contained in set B
