Amplitude Fitting and Sine Function Demonstration

This example demonstrates how to fit a sine function using GeoGebra's FitSin command, showcasing parameter variations like amplitude and period. Core mathematical concepts include sine functions, amplitude, period, circumcircle of a circle, confidence intervals, and equations. The construction utilizes commands like FitSin and Textfield, along with objects such as A, B, C, D, f, a_1, amp, amplitude, g. Suitable for high school and above learners for understanding trigonometric function graph fitting and parameter analysis.
