U+2243 "≃" Asymptotically Equal To Unicode Character

U+2243 "≃" Asymptotically Equal To is a mathematical symbol used to denote that two quantities or functions are approximately equal, but with a more precise connotation of approaching the same value or behavior, particularly as a variable tends toward a limit, such as in calculus or asymptotic analysis. It differs from the similar tilde operator or the almost equal to symbol by suggesting a relationship that holds in the limit, often with the implication that the difference between them becomes negligible relative to their magnitude. This character is commonly employed in mathematics, physics, and engineering to indicate that two expressions are equivalent in an asymptotic sense, like when a function approximates a simpler form for large values.
