Question Analysis  

Determine the relationship between and for the unit circle coordinates of , leveraging the symmetry of 45-45-90 triangles.  

 

Key Concept Explanation  

45-45-90 Triangle on Unit Circle: The coordinates are , where due to equal legs in the triangle.  

 

Step-by-Step Solution  

1. Recall 45° coordinates:  

, .  

2. Analyze the relationship:  

Since both values are equal, .  

 

Option Analysis  

: Incorrect (would imply x > y, but )

: Incorrect (same as above; contradicts equality)
