Math Problem Statement
What are the new coordinates of point A after a 90° clockwise or 270° counterclockwise rotation around the origin?
Solution
The image provides a transformation rule, specifically for a 90° clockwise or 270° counterclockwise rotation around the origin. The formula for the transformation is:
The question involves determining the new coordinates of point after applying this transformation.
From the graph:
