Hello everyone
I have a question, and ill use an example to ask it.
I want to find all 0<x<2π which sin(x) will equal -0.5.
So I punch in a calculator:
arcsin(-0.5)
I get -π/6.
I add 2π to it and I get 11/6π which is cool.
But of course there's one more x that can be used and my question is how to find it.
(Its 7/6π and my book didn't explained how to find it)
Any suggestions?
Thank you very much.
