\simeqThe symbol \simeq is used to denote that two quantities are asymptotically equivalent or approximately equal in some context. It is often used in mathematics to express that two functions or sequences have the same behavior as they approach a certain limit.
The functions f(x) and g(x) are asymptotically equivalent as x approaches infinity.
f(x) \simeq g(x) \text{ as } x \to \inftyThe sequences a_n and b_n are approximately equal for large values of n.
a_n \simeq b_n \text{ for large } nThe expression x^2 + x is approximately equal to x^2 for large values of x.
x^2 + x \simeq x^2 \text{ for large } x
