AI Drawing Prompt Reference

Draw a unit circle and the graph of the sine function to illustrate its geometric derivation. Place a moving point on the sine curve, then construct a tangent line at that point and display its slope. Also draw a segment from this point to the corresponding point on the unit circle, showing the relationship between the sine value and the y-coordinate of the circle point. Include coordinate axes, the unit circle, the sine curve, the moving point, the tangent line, the slope label, and the connecting segment. The layout should be clear and suitable for high school teaching.
