Ja, aber da gibt es schlimmeres aus der Vergangenheit von mir zu lesen...hoffe ich.Ihr wisst, dass jeder diese Peinlichkeiten lesen kann.
Die Kurve werde ich nicht mehr kriegen aber jetzt hab ich bei Wiki nachgeschaut.

The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense.[1] In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the same value.
The triple bar or tribar, ≡, is a symbol with multiple, context-dependent meanings indicating equivalence of two different things. Its main uses are in mathematics and logic. It has the appearance of an equals sign ⟨=⟩ with a third line.
The triple bar symbol ≡ (U+2261, LaTeX \equiv) is often used to indicate an identity, a definition (which can also be represented by U+225D ≝ EQUAL TO BY DEFINITION or U+2254 ≔ COLON EQUALS), or a congruence relation in modular arithmetic. Also, in chemistry, the triple bar can be used to represent a triple bond between atoms.
In mathematics, an identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B (which might contain some variables) produce the same value for all values of the variables within a certain range of validity.[1] In other words, A = B is an identity if A and B define the same functions, and an identity is an equality between functions that are differently defined. For example,andare identities.[1] Identities are sometimes indicated by the triple bar symbol ≡ instead of =, the equals sign.[2] Formally, an identity is a universally quantified equality.
