This Trigonometric Functions lesson plan also includes:
From a circle to a cycle! The final lesson plan of a five-part series challenges learners to use points from the unit circle to plot a repeating pattern. The repeating patterns become the graphs of the trigonometric functions. Scholars also identify the characteristics of the functions such as period, frequency, and amplitude.
- Have individuals record characteristics for each graph for comparison
- Compare and contrast graphs of the sine, cosine, and tangent function
- Requires a strong understanding of the unit circle relationships
- Graph paper has a unit circle graphed for a direct comparison to the graph of the trigonometric function
