darr

Represents a downward-pointing arrow, commonly used to indicate vertical direction, descent, or decreasing values in mathematical expressions.

Overview

Serves as a versatile directional indicator in mathematical notation, technical diagrams, and scientific documentation.

  • Frequently used in computer science to show hierarchical relationships or data flow
  • Applied in mathematics to denote decreasing sequences or functions
  • Common in economics and statistics to indicate downward trends or declining values
  • Appears in chemistry to show precipitation or downward reaction pathways

Examples

Showing a decrease in a mathematical sequence or trend

xn0 as nx_n \darr 0 \text{ as } n \to \infty
x_n \darr 0 \text{ as } n \to \infty

Indicating downward movement in a physical system

F=mgF_{\darr} = -mg
F_{\darr} = -mg
