Answer:
On a unit circle, the point that corresponds to an angle of is at position .
The point that corresponds to an angle of is at position .
Step-by-step explanation:
On a cartesian plane, a unit circle is
- a circle of radius ,
- centered at the origin .
The circle crosses the x- and y-axis at four points:
Join a point on the circle with the origin using a segment. The "angle" here likely refers to the counter-clockwise angle between the positive x-axis and that segment.
When the angle is equal to , the segment overlaps with the positive x-axis. The point is on both the circle and the positive x-axis. Its coordinates would be .
To locate the point with a angle, rotate the segment counter-clockwise by . The segment would land on the positive y-axis. In other words, the -point would be at the intersection of the positive y-axis and the circle. Its coordinates would be .
