AI Drawing Prompt Reference

Draw a geometric illustration of the derivative function. Include a curve representing the function, a point on the curve, a tangent line at that point, and the slope. Describe how these elements show the derivative: the tangent line has the same slope as the curve at the point of contact. The construction order should start with the function curve, mark a point, construct the tangent line, and calculate the slope. The illustration should clearly show the relationship between the derivative and the tangent, suitable for math education.
