Find the coordinate point of the given angle

The video tutorial explains how to find a point on the unit circle for the angle T = -3π/4. It emphasizes the importance of recognizing negative angles and how to navigate the unit circle in a negative direction. The tutorial breaks down the unit circle into fractions and identifies the terminal side of the angle. It then calculates the coordinates in the third quadrant, highlighting that both x and y values are negative. The tutorial concludes with a summary of the coordinate point at the given angle.

What is the significance of the negative sign in the angle -3π/4?

• It suggests the angle is in the first quadrant.

• It indicates a clockwise direction on the unit circle.

• It means the angle is larger than π.

• It shows the angle is measured in degrees.

How is π divided to locate the angle -3π/4 on the unit circle?

• Into four parts

• Into two parts

• Into six parts

• Into three parts

What is the reflection of a point on the unit circle?

• A point that is in the same quadrant

• A point that is at the same distance from the origin

• A point that is at the same angle but different radius

• A point that is directly opposite on the circle

In which quadrant is the angle -3π/4 located?

• First quadrant

• Second quadrant

• Third quadrant

• Fourth quadrant

What are the coordinates of the point at angle -3π/4 in the third quadrant?

• (sqrt 2 / 2, sqrt 2 / 2)

• (-sqrt 2 / 2, -sqrt 2 / 2)

• (-sqrt 3 / 2, -sqrt 3 / 2)

• (sqrt 3 / 2, sqrt 3 / 2)
