Learn how to evaluate the sine inverse of negative 1 half

The video tutorial explores when the sine of an angle equals -1/2 using the unit circle. It identifies angles with the same reference angle as π/6 and discusses the inverse sine function's restrictions. The tutorial concludes by determining the correct angle within these restrictions, emphasizing the importance of understanding the unit circle and inverse functions.

Why is the answer to the sine inverse of -1/2 equal to -π/6?
