Math Problem Statement
Solution
The problem asks to find the coordinates of the point on the unit circle corresponding to the angle .
Step-by-Step Solution:
-
Interpret the angle:
The angle is a negative angle, so it is measured in the clockwise direction.To find the equivalent positive angle, we can add to : This means is coterminal with , which corresponds to the positive y-axis on the unit circle.
-
Determine the coordinates:
The angle points directly upwards on the unit circle. The coordinates of this point on the unit circle are:
Therefore, the coordinates of the point corresponding to are .
