Addition of Two Sines

This example demonstrates the graphical phenomenon of adding two sine functions. It involves core mathematical concepts such as sine functions, trigonometry, coordinate geometry, and matrix operations. The construction utilizes GeoGebra commands/objects like Segment, G1C, f1, R1, t, f2, G2C, R2, G2, R2_1, G1, g, f, B, h, i. It is suitable for high school students learning and understanding the superposition and transformation rules of function graphs.
