No Evidence for Babylonian Cotangent 2:1 Ratio or Sexagesimal Octave Harmonics — E8 Intelligence Research

FINDING: Search returned no evidence of a "Babylonian cotangent 2:1 ratio" or sexagesimal harmonic octave mathematics; the query's target concept is absent from the retrieved corpus. | MATH: Only tangentially relevant item is BM 85200 no.6/no.7 and YBC 4669 B2 (cubic equations, Old Babylonian, sexagesimal). No cotangent tables, no 2:1 ratio, no octave-harmonic claim appears. | CONNECTION: None supported. Base-60 is present only as the ambient numeral system of the Babylonian cubics, not as a demonstrated harmonic/octave structure. | DEPTH: 1 FINDING: The remaining four results are unrelated to ancient mathematics — two are GNU Octave software papers (biomedical signal processing; fractional optimal control), two are modern algebraic-geometry cotangent complexes (FW-cotangent bundle; Frobenius–Witt cotangent complex). | MATH: Octave ≠ octave. "Cotangent" here denotes the cotangent bundle/complex in algebraic geometry and the cotangent function in control theory — homonyms, not the trig Author: Andrew Stewart Caldin, Independent Researcher, UK.
