Arrows in LaTeX FAQ
What is the difference between \Rightarrow and \implies?▼
\Rightarrow creates a standard double right arrow (⇒). In the amsmath package, \implies adds extra mathematical spacing around the arrow and renders a longer double arrow (⟹) recommended for formal proofs and logical consequences.
How do I denote function mappings with \mapsto vs \rightarrow?▼
In mathematics, \rightarrow indicates the function signature between sets (e.g., f: X \rightarrow Y), while \mapsto indicates what happens to a specific element (e.g., x \mapsto x^2).
How do I represent chemical equilibrium in LaTeX?▼
Use \rightleftharpoons for standard two-way equilibrium arrows (⇌) or \leftrightharpoons from the amssymb package.
How do I write long arrows in LaTeX?▼
Prefix standard arrow names with "long", such as \longrightarrow (⟶), \longleftarrow (⟵), \Longrightarrow (⟹), and \longleftrightarrow (⟷).
