AI Drawing Prompt Reference

Create a graphing workspace for building and solving a trigonometric equation with parameter inputs: include five user-editable input boxes for the equation’s parameters, then plot the equation-related curve and determine a specific intersection point under a fixed numerical constraint. Convert the intersection’s x-coordinate into a displayed value by taking the ratio to pi and show it as text. Add a second text that reports whether any digits repeat based on the computed text’s length. Finally, add two additional input boxes for further parameters to continue the construction and checks.
