State the Domain of the Inverse Sine Function

Показать описание
Inverse Sine's DOMAIN is the same as the RANGE of regular sine.
Which means it's between -1 and 1 (inclusive)
I also show this graphically and why we call "inverse sine" a FUNCTION even though it looks like it fails the vertical line test.

Nice video!
The highest and lowest values of the inverse are actually ±π/2 as sine has its maximum/minimum (±1) values at ±π/2
