Finding the Inverse of the Sine Function

The video tutorial explains how to find the inverse sine of a given value. It starts by introducing the concept and then uses the unit circle to identify possible angles where sine equals 1/2. The focus is on positive values, eliminating negative possibilities. The tutorial then determines the valid angle within the range of -π/2 to π/2, concluding that the inverse sine of 1/2 is π/6. It also mentions the use of a chart for checking work but emphasizes understanding the process without it.

Why can't the inverse sine function take on negative values in this context?

What is the final conclusion about the inverse sine of 1/2?
