Use the equation and solve the problem

Question

Sin x= -0.32 on [0,2π)

Answer 1

With calculator in RADIANS mode, do sin^-1 (-0.32) = -0.326 rad. One solution is just adding 2π to this, giving 5.957 rad. Second answer via a sketch: the other angle having the same sine value lies a little below the negative x-axis or the ray to π radians, so it is π + 0.326 = 3.467 rad.
