smallint

Displays a smaller version of the standard integral symbol, ideal for inline mathematical expressions and compact notation.

Overview

Provides a space-saving alternative to the standard integral symbol while maintaining readability in mathematical formulas. Particularly valuable in:

  • Inline mathematical expressions where vertical space is limited
  • Multi-integral expressions where standard-sized symbols might appear too dominant
  • Technical documents where compact notation is preferred
  • Journal submissions with strict spacing requirements

Commonly found in advanced mathematics texts and physics papers where multiple integrals appear in a single line or where space optimization is crucial.

Examples

Computing a simple definite integral with a smaller integral symbol.

∫01x2dx=13\smallint_0^1 x^2 dx = \frac{1}{3} 
\smallint_0^1 x^2 dx = \frac{1}{3}

Line integral around a closed curve using smaller notation.

∫CF(z) dz=2πi\smallint_C F(z)\,dz = 2\pi i 
\smallint_C F(z)\,dz = 2\pi i

Double integral with compact notation for better inline readability.

∫∫Dxy dx dy=14\smallint\smallint_D xy\,dx\,dy = \frac{1}{4} 
\smallint\smallint_D xy\,dx\,dy = \frac{1}{4}
