This example allows you to input functions and use geometry to abstract information from the function, involving trigonometric functions, vectors, and coordinate geometry. Commands used include semicircle, segment, circle, polygon, vector, angle, point, distance, intersect, mirror, textfield, slope, rotate, etc. Suitable for high school and above students or teachers.
