WebJan 2, 2024 · Beginning Activity. In this section, we will study the graphs of functions whose equations are f(t) = Asin(B(t − C)) + D and f(t) = Acos(B(t − C)) + D where A, B, C, and D are real numbers. These functions are called sinusoidal functions and their graphs are called sinusoidal waves. We will first focus on functions whose equations … WebAny situation that is based on circular motion may be modeled by a sinusoid, including the phases of the moon, day length as a function of the season, or tides. As Noble notes, the sine and cosine also describe periodic motion where the acceleration is proportional and opposite to the position -- including EM waves, sound waves, and coil springs.
