Sin x = 2/pi

How do you solve for x?? I am drawing a blank!

I did sin-1 ( 2/pi) = 0.69 but I need another value cause I am also supposed to get 2.451???

sin(x) is periodic with period 2*pi. There are many solutions to sin(x)=2/pi. 2.451 is one of the 'other ones' outside of the range of sin^(-1). Draw a graph.
