The ∽ symbol, officially known as the Reversed Tilde, is a mathematical operator that visually mirrors the standard tilde. In mathematics and physics, it is used to denote equivalence relations, proportionality, or specific asymptotic behaviors when a distinct symbol from the regular tilde is required. Outside of technical fields, it occasionally appears in creative typography or text-based art to represent flowing waves.
