Question Analysis  

The main focus is to determine the coordinates on the unit circle corresponding to the angle (60°), using trigonometric functions (cosine and sine).  

 

Key Concept Explanation  

On the unit circle, the coordinates of a point at angle are given by . For special angles like , these values are derived from equilateral triangle properties or memorized unit circle ratios.  

 

Step-by-Step Solution  

1. Recall special angle values:  

 

 

2. Write coordinates:  

The point is
