From the unit circle, the sine values that equal 1/2 have the solution set x = π/6+2πn, 5π/6+2πn. π/2⋅x = π/6+2πn, 5π/6+2πn. x = 1/3+4n, 5/3+4n. Since we are looking for the 4 smallest positive solutions, we would need to plug in n=0 and n=1: x = 1/3+4 (0), 5/3+4 (0)

WebMar 15, 2015 · This also answers what the meaning of p X, Y ( x, y) is: It is the joint probability of obtaining the values X = x and Y = y, so for instance, p X, Y ( 1, 3) = 0.3, as read from your table.
