Limaçon

A Limaçon is a type of mathematical curve, specifically a polar curve, characterized by its unique, rounded shape. It can look like a distorted circle or have a "dimple" or even a loop, depending on its parameters. The name comes from the French word for "snail," reflecting its snail-like appearance in certain forms. Limaçons can be studied in geometry and are used in various fields such as engineering and physics to model certain shapes and designs. The equation for a Limaçon involves trigonometric functions, which dictate its distinctive form.
