Evaluate the six trigonometric functions for the given real number

The video tutorial explains how to evaluate the six trigonometric functions for a point on the unit circle, specifically at the point (-1, 0). It covers the concepts of angle rotation, the unit circle, and the reflection of points. The tutorial details the evaluation of sine, cosine, tangent, and their reciprocal functions, highlighting cases where functions are undefined due to division by zero.

What is the significance of rotating an angle counterclockwise on the unit circle?

• It represents a negative angle.

• It represents a positive angle.

• It has no significance.

• It represents a full circle.

What are the coordinates of the point where the angle π intersects the unit circle?

• (0, 1)

• (1, 0)

• (-1, 0)

• (0, -1)

How is the sine of an angle determined on the unit circle?

• By the Y coordinate of the point.

• By the difference of X and Y coordinates.

• By the sum of X and Y coordinates.

• By the X coordinate of the point.

What is the value of the secant function for the point (-1, 0) on the unit circle?

• 0

• 1

• -1

• Undefined

Why is the cosecant function undefined for the point (-1, 0) on the unit circle?

• Because the Y coordinate is zero.

• Because the angle is negative.

• Because both coordinates are zero.

• Because the X coordinate is zero.
