Function, Derivative, and Tangent Demonstration

This example demonstrates the graphs of a function f(x) and its derivative f'(x) in a coordinate system, along with the tangent at a specified point A. Core mathematical concepts include functions, derivatives, tangents, and coordinate geometry. Construction highlights: the Tangent command is used to draw the tangent, the Textfield command adds text explanations, and objects include the function f, derivative f', point A, and input boxes inputBox1 and inputBox2. Suitable for high school and above students learning calculus and analytical geometry to understand function properties and tangent calculations.
