Hyperbola

What is a hyperbola? As we all know, it is a perfectly symmetrical figure in the field of mathematics. But recently there has been a new statement. Some people say that a hyperbola is the shape of two tall wine glasses placed flat with their backs facing each other; the middle part of the hyperbola looks like an exquisite coffee cup, so the hyperbola will be used as a signboard of Internet cafes by creative people. Some people say that a hyperbola is the shape of a □, so it implies certain loves and certain characters. These loves, these characters, are just like the hyperbola itself. Although they can be as close as possible, they are destined not to merge. Others believe that the hyperbola is actually the handwritten letter "x", which is a well-known unknown quantity. Therefore, its mystery is unparalleled. What exactly is a hyperbola? The answers can be said to be endless, and maybe everyone will have a unique insight. But no matter what, we at least know one fact: the hyperbola extends infinitely in space and has no end. Its mystery and tragedy span the time since the beginning of mankind and have no end either. Some experiences of some people are just a cross-section of it at a certain moment.
