In this Algebra 2 lesson, students learn how to model real-world scenarios using sine and cosine functions, two key trigonometric functions used to represent periodic behavior. Without graphing, students focus on interpreting and writing sinusoidal equations by analyzing parameters such as amplitude, period, phase shift, and vertical shift in meaningful contexts like temperature patterns, tides, seasonal trends, or motion.

Students will write equations based on descriptions of real-world situations and from provided graphs, building fluency in translating between contextual information and algebraic representations of periodic functions.

This resource includes guided notes, structured practice, and a formative assessment in the form of an exit ticket to support conceptual understanding and build fluency.

This no-prep resource includes everything you need for a full class period.
