AI Drawing Prompt Reference

Create a dynamic educational diagram illustrating parametric curves and geometric mean. Include two randomly generated parametric curves with adjustable coefficients, plus two input boxes for parameter values. Display a data table showing function outputs for various inputs, highlighting special points related to the geometric mean. The layout should be clear for classroom use, emphasizing how parameter changes affect curve shapes and the geometric mean calculation.
