Curves
Open with main menu g, then Games 7.
Nine common curves sampled and polyline-drawn in real time. Adjust amplitude a, frequency b, and phase p, and toggle phase animation.

Notes
- Top-left shows the curve name and formula; top-right shows params and
RUN/PAUSE. - With animation on, phase advances with frequency; axes are centered and the curve is drawn as a cyan polyline.
- Parametric curves (circle / heart / Lissajous) use denser sampling (180 points); function curves use 120.
