Derivative of Arcsine Function

This example demonstrates how to investigate the derivative of the arcsine function f(x) = arcsin(x) through dynamic geometry. Key math concepts include the geometric interpretation of derivatives, properties of trigonometric functions, and limit concepts. Construction highlights the use of GeoGebra commands/objects like Point, Intersect, Circle, Tangent, Slope, Vector, and Textfield to visualize the changing slope of tangents. Suitable for high school calculus instruction to help students intuitively understand abstract derivative definitions and calculations.
