Find the coordinate point of the given angle

The video tutorial explains how to find the point on the unit circle corresponding to the angle t = π. It begins by introducing the unit circle and its radius of 1. The tutorial then describes how the angle t = π represents halfway around the circle, leading to the coordinate point (-1, 0). The explanation includes the reflection over the Y-axis and concludes with a summary of the process.

What is the radius of the unit circle?

• 0.5

• 1

• 2

• π

What is the coordinate point on the unit circle for the angle π?

• (1, 0)

• (0, 1)

• (-1, 0)

• (0, -1)

How is the point for angle π on the unit circle related to the Y-axis?

• It is a reflection over the X-axis.

• It is a reflection over the Y-axis.

• It is not related to the Y-axis.

• It is a reflection over the origin.

What fraction of a revolution does the angle π represent on the unit circle?

• 1/2

• 1/4

• 1

• 3/4

Where does the angle π start and end on the unit circle?

• Starts at (1, 0) and ends at (0, 1)

• Starts at (1, 0) and ends at (-1, 0)

• Starts at (-1, 0) and ends at (1, 0)

• Starts at (0, 1) and ends at (-1, 0)
