I just have a simple question as to which radians to use in calculating phase constants in oscillations.(adsbygoogle = window.adsbygoogle || []).push({});

For example in sin(theta) = 1/2, do I use the (pi)/6 or 5(pi)/6?

The exact question has a diagram and is difficult to explain, but I just want a general explanation.

Thank you!
