How do i solve this equation?

sin((pi/4)(x-6))=0.5 The answer is 1.33 but i don't know how to get it, thank you.

EDIT: Between 0-2pi

[quote=MarshMallows]Both answers are actually correct. Since sine is a periodic function, there's multiple answers since sine oscillates between -1 and 1 in your problem from -infinity to infinity.
If you want an answer that's positive and closest to 0, then it's 1.33[/quote]
Ah, i understand it a bit now. Thank you. Thanks everyone for their contribution!

Well, if you plug in 1.33 it yields 0.5.
