When solving trig equations Why is the domain restricted?

It means that we are limiting the possible values that our variable can be. Because we are working with trigonometric equations, our variable will be in radian units. So, you will most likely see a pi in the restricted domain. For example, you might see f(x) = sin (x) + 2; 0 < x < pi.
