AI Drawing Prompt Reference

Draw a function graph and select two points A and B on it to form a segment f. Calculate the length of f and display it. Input two numbers j and k to find point C on a specific circle using j and k as parameters, then form segment l by connecting AC. Check if the length of l meets the requirement and display the result. Find point D on the function graph and form trapezoid t1 by connecting AD and DB. Calculate the angle BAD and display it.
