Set M = {x | 2K π ≤ x ≤ 2K π + π, K belongs to Z} n = {x | - 6 ≤ x ≤ 6} Then the intersection of M and n=

M denotes the area above the x-axis and the x-axis, i.e. - 360 °≤ x ≤ - 180 °, 0 °≤ x ≤ 180 °, 360 °≤ x ≤ 540 ° and so on. In N, - 6 and 6 should be arc system. 1 arc is about 57.3 ° and 6 arc is about 343.8 ° so n = {x | - 343.8 °≤ x ≤ 343.8 °} so the intersection is {x | - 343.8 °≤ x ≤ - 180
