\backsim
The \backsim symbol is used to denote similarity or equivalence in mathematics. It is often used in geometry to indicate that two figures are similar, meaning they have the same shape but possibly different sizes. In statistics, it can also represent that two distributions are similar or that a random variable follows a certain distribution.
Indicates that triangle ABC is similar to triangle DEF in geometry.
\triangle ABC \backsim \triangle DEF
Represents that random variable X is similar to random variable Y in statistics.
X \backsim Y
Indicates that function f(x) is asymptotically similar to function g(x) as x approaches a limit.
f(x) \backsim g(x)
