Common Core Algebra 2, Unit 10
Unit 10 in the Common Core Algebra 2 series focuses on graphing sine and cosine. Learners discover how to find the amplitude and midline, both from the graphs and the function in standard form. They then graph sine and cosine with different amplitudes and midlines. For the second lesson in the series, pupils learn the definition of period and find out how to determine it both from the graph and the equation of the function. Finally, scholars use their knowledge of trigonometric functions to model periodic motions like Ferris wheels. The unit concludes with a review of the amplitude, midline, period, and frequency of sinusoidal functions. Individuals then demonstrate what they have learned by using a function to model a situation and to interpret values within the context.
