AI Drawing Prompt Reference

Create a trigonometric expression using four randomly generated integers between -10 and 10, such as a*sin(b*x+c)+d*cos(e*x+f), and display it in an input box. Randomly select an operation, such as evaluation or substitution, and show the corresponding expression in another input box.
