AngleTrigonometryCalculusProbability & StatisticsGeometric Construction
This example dynamically illustrates geometric and probability phenomena including angles, ratios, conditional probability, geometric mean, upper and lower sums or Riemann sums, and trigonometric functions. It leverages commands like CurveCartesian, Segment, Circle, Intersect, CircleArc, Angle, Ray, Vector, Mirror from the construction summary. Suitable for high school and above, it helps in understanding complex geometric and probability models.

AI Drawing Prompt Reference

Create a dynamic illustration showing geometric and probability concepts, including a spiral, angles, arcs, and rays. Begin with a spiral originating from the origin, then mark angles and arcs on it. Add a circle perpendicular to the spiral and draw rays and vectors at the intersection points of the circle with the x-axis. Finally, demonstrate the dynamic changes of geometric mean, conditional probability, and trigonometric functions.
