Locate $-pi/2$ on a Unit Circle

Answer 1

Abigail Nelson

John Anderson

To locate $-\pi/2$ on the unit circle, we can follow these steps:

1. Start at the positive x-axis (0 radians).

2. Move clockwise because the angle is negative.

3. Since $-\pi/2$ radians equals -90 degrees, move 90 degrees clockwise from the positive x-axis.

4. This will place you on the negative y-axis.

Therefore, the coordinates for $-\pi/2$ on the unit circle are (0, -1).

Answer 2

Here is how to find the position of $-pi/2$ on the unit circle:

1. Begin at the starting point on the unit circle, which is at $(1, 0)$ on the positive x-axis.

2. Move in a clockwise direction as the angle $-pi/2$ is negative.

3. $-pi/2$ radians is equivalent to moving 90 degrees clockwise.

4. This movement will end at the negative y-axis.

Thus, the coordinates of $-pi/2$ on the unit circle are (0, -1).

To find $-pi/2$ on the unit circle:

1. Start at (1, 0) on the positive x-axis.

2. Move 90 degrees clockwise.

3. You will land on the negative y-axis.

Therefore, the coordinates are (0, -1).
