Reflecting Sine and Cosine Curves Across Vertical Lines
1. How does the graph of sine reflected across the line x = π appear? 2. Move the vertical line. When is there bilateral symmetry? 3. Summarize your findings. 4. Turn off the sine function. 5. Turn on the cosine function. 6. When does the reflection and the original curve have bilateral symmetry? 7. Summarize as you move the reflecting line.
