Title: Understanding θ = 35° + 15° · sin(2πt / 365): A Mathematical Model of Seasonal Cycles --- Introduction In the study of seasonal variations and periodic phenomena, trigonometric equations play a crucial role in modeling cyclical behavior. One such equation—θ = 35° + 15° · sin(2πt / 365)—offers a precise yet elegant way to represent cyclical patterns over a year, commonly used in climatology, epidemiology, economics, and natural sciences. This article explores the mathematical components, real-world applications, and significance of this equation.
