vartheta

Represents an alternate form of the Greek letter theta, providing a more cursive or script-like variant commonly used in mathematical notation.

Overview

Serves as a stylistic alternative to the standard theta symbol, particularly useful when multiple theta variables are needed in the same equation or mathematical context.

  • Often employed in physics and engineering to distinguish between related angular measurements or parameters
  • Frequently appears in mathematical optimization, thermodynamics, and complex analysis
  • Preferred in contexts where visual distinction from regular theta enhances clarity of notation
  • Commonly used alongside regular theta (θ) when parallel or related concepts need distinct representation

Examples

Angular displacement in physics equations.

ω=dϑdt\omega = \frac{d\vartheta}{dt}
\omega = \frac{d\vartheta}{dt}

Phase angle in complex analysis.

z=reiϑz = re^{i\vartheta}
z = re^{i\vartheta}

Spherical coordinates in mathematics.

x=rsinϑcosϕx = r\sin\vartheta\cos\phi
x = r\sin\vartheta\cos\phi
