Determine the position of $ -frac{pi}{2} $ on a unit circle
Answer 1
Chloe Evans
To find the position of $ -\frac{\pi}{2} $ on a unit circle, we start by understanding that the unit circle is a circle with radius 1 centered at the origin (0,0). The angle $ -\frac{\pi}{2} $ is measured in the clockwise direction from the positive x-axis.
In standard position, the angle $ -\frac{\pi}{2} $ corresponds to the point where the terminal side intersects the unit circle. This is the negative y-axis.
Thus, the coordinates of this point are:
$ (0, -1) $

Benjamin Clark
To locate the coordinates of $ -frac{pi}{2} $ on the unit circle, we start from the positive x-axis and move clockwise by an angle of $ -frac{pi}{2} $. This brings us to the negative y-axis.
The corresponding coordinates on the unit circle are:
$ (0, -1) $
