Find the values of x for which the equation sin x = 1 is true
2 pi n
pi/2 + 2 pi n
pi + 2 pi n
3 pi/2 +2 pi n
Can someone please help. I don't understand how to do this.

Sin x = 1 when x is 270 degrees, which is 3 pi/2 radians. If you add (2 n pi) to that, where n is an integer, you get the same value for the sin.
Therefore the correct answer is the last one.
