AI Drawing Prompt Reference
Draw the graph of a multivariable function and illustrate the geometric meaning of its first and second partial derivatives. Add two perpendicular vectors to the function graph, representing the rates of change in the x and y directions. Use curves to show the level sets of the function and different vectors to represent the first and second partial derivatives, demonstrating their relationship with the function graph.
