underrightarrow

Creates a right-pointing arrow underneath text or mathematical expressions, commonly used to indicate directed segments or transformations.

Overview

Particularly valuable in mathematical notation where directional relationships or transformations need to be emphasized beneath symbols or expressions.

  • Essential in geometric contexts for denoting directed line segments or vectors
  • Used in abstract algebra to show mappings or transformations
  • Common in category theory for representing morphisms
  • Helpful in teaching materials to emphasize direction or progression
  • Often paired with mathematical expressions to indicate motion or change

Examples

Showing a directed line segment between two points in geometry.

AB‾AB→\overline{AB} \underrightarrow{AB} 
\overline{AB} \underrightarrow{AB}

Indicating a vector with direction in physics notation.

v→=v0→+a⃗t\underrightarrow{v} = \underrightarrow{v_0} + \vec{a}t 
\underrightarrow{v} = \underrightarrow{v_0} + \vec{a}t

Representing a directed transformation or mapping between spaces.

Xf→YX \underrightarrow{f} Y 
X \underrightarrow{f} Y
