varsigma

Represents a variant form of the lowercase Greek letter sigma, providing a stylistic alternative in mathematical notation.

Overview

Serves as a distinct visual variant of the standard sigma symbol, particularly useful when multiple sigma-like variables are needed in the same context.

  • Common in mathematical writing where visual distinction between similar Greek letters is important.
  • Often employed in statistical notation and complex mathematical expressions.
  • Provides an aesthetically different option while maintaining the sigma family connection.
  • Particularly useful in contexts where both regular sigma and varsigma are needed to represent different variables or concepts.

Examples

Using varsigma as a variable in a mathematical function definition.

f(ς)=ς2+2ς+1f(\varsigma) = \varsigma^2 + 2\varsigma + 1 
f(\varsigma) = \varsigma^2 + 2\varsigma + 1

Representing a specific angle in a geometric equation.

cos⁡(ς)=32\cos(\varsigma) = \frac{\sqrt{3}}{2} 
\cos(\varsigma) = \frac{\sqrt{3}}{2}

Using varsigma as an integration variable in calculus.
