Question

Which point on the unit circle corresponds to -π?

(0,-1)



(1,0)



(0,1)



(-1,0)

Answer 1

The point on the unit circle that corresponds to -π is (0, -1).

The unit circle is a circle with a radius of 1 centered at the origin (0, 0) in a Cartesian coordinate system. It represents the values of the trigonometric functions for various angles.

In this case, -π represents an angle of π radians in the clockwise direction. At this angle, the x-coordinate is 0 and the y-coordinate is -1, which corresponds to the point (0, -1) on the unit circle.
