AI Drawing Prompt Reference

Draw a family of circles centered at point A with radii 0.5, 1, 1.5, 2, and 2.5, then draw a ray h from point A that intersects each circle at points B, G, I, and K. Draw another ray i from point A that intersects ray h to form angle α. Finally, connect points B, G, I, and K to approximate a hyperbola, illustrating the relationship between indefinite integrals and multiplication.
