語源 1

From Proto-Indo-European *sinos; akin to Albanian gji ‘breast, bosom’.^[1]

The mathematical sense ‘chord of an arc, sine’ was introduced in the 12th century by Gherardo of Cremona as a semantic loan from Arabic جَيْب‎ (jayb, “chord, sine”) (ultimately a loan from Sanskrit ज्या (jyā, “bowstring”)) by confusion with جَيْب‎ (jayb, “bosom, fold in a garment”).
