Fitting the Sine Function

This example demonstrates how to fit a sine function by adjusting parameters. It involves core math concepts like trigonometry, sequences and series, similarity transformation, and differential equations. Constructed using commands like Random and Textfield, along with objects such as A, C, D, B, f, a, b, c, d, g for geometric and functional operations. Suitable for high school and above students to understand function fitting and parameter adjustment applications.
