WebIn mathematics (particularly in complex analysis), the argument of a complex number z, denoted arg(z), is the angle between the positive real axis and the line joining the origin and z, represented as a point in the complex plane, shown as in Figure 1. It is a multivalued function operating on the nonzero complex numbers.To define a single-valued function, …

There are multiple values that would satisfy this relationship, such as π 6 π 6 and 5 π 6, 5 π 6, but we know we need the angle in the interval [− π 2, π 2], [− π 2, π 2], so the answer will be sin − 1 (1 2) = π 6. sin − 1 (1 2) = π 6. michel thomas french reddit
