Anticlockwise Integration Symbol
⨑ denotes an anticlockwise integration, commonly used in math notation to indicate orientation.
U+2A11
The symbol ⨑ is used in mathematical writing to suggest an anticlockwise orientation in an integration context. It’s a specific Unicode character (U+2A11), so it’s convenient for typed math and documentation. You can copy it directly or use standard HTML and code escapes.
Anticlockwise Integration Symbol Meaning
⨑ (Unicode name: “ANTICLOCKWISE INTEGRATION”) is a mathematical symbol that indicates an integration performed with an anticlockwise orientation. In practice, orientation matters when describing contour integrals, parametrized paths, or circulation-like quantities where reversing direction changes the result’s sign or meaning. Authors use ⨑ to make the chosen traversal direction explicit rather than relying on surrounding text. Because it is a dedicated character in the Unicode “Math” category, it works well in plain text, code comments, and lightweight documents without needing a custom font glyph for a similar concept.
Common uses
- •Labeling or annotating contour integrals with anticlockwise direction
- •Writing notes for complex analysis problems where direction affects sign
- •Formulating physics or engineering explanations involving oriented loops
- •Typing mathematical derivations in documents that accept Unicode math symbols
- •Creating consistent symbol keys in worksheets and educational materials
Examples
⨑ Anticlockwise Integration Symbol
- ⨑Compute the integral ⨑∫ f(z) dz along the anticlockwise path.
- ⨑Let C be oriented anticlockwise; write the contour integral using ⨑.
- ⨑For the closed curve, take ⨑∫_C to indicate the traversal direction.
- ⨑When reversing direction, compare results with and without ⨑.
- ⨑In the solution, the anticlockwise integral is marked with ⨑∫.
