AI Drawing Prompt Reference
Create a cosmic model based on circular motion, featuring multiple rotating circular paths with varying radii and angles. Start by drawing two circular paths, then rotate these paths around a central point using specific mathematical expressions for the radii and angles. Pay attention to the relationship between the rotation angle and the radius of each path.
