Figure 1: The Reflect Family
- Use the first three tools to construct independent variable x and reflect it across a mirror.
- Observe the behavior of dependent variable rj(x), and turn on tracing to make an interesting pattern.
- What is the relative speed of the variables? What is their relative direction?
- Where can you drag x? As you drag x, where can you make rj(x) go?
