Plotting a Sine Wave
30-minute lesson · module-lab-sine-wave
- Use the `math` module — specifically `math.sin` and `math.radians`.
- Build parallel lists of x and y values across a range with a list comprehension.
- Distinguish degrees from radians and convert between them.

Adaptation notes. Original lab used the turtle module to plot the wave point-by-point. We replace turtle with returning the (x, y) sample pairs. A follow-up note shows how to feed the same data into matplotlib for an actual visual plot (Pyodide supports matplotlib via micropip). The math — `math.sin(math.radians(angle))` — is preserved.
