Find ALL possible values of sin-1 (-1/2)
Added by Jacqueline L.
Step 1
First, we need to identify the angle whose sine is -1/2. We know that sine is negative in the third and fourth quadrants of the unit circle. In the third quadrant, the reference angle whose sine is 1/2 is 30 degrees or pi/6 radians. However, since sine is negative Show more…
