  2. I saw the Sine Jya Abbreviated form of “Jya-ardha” meaning“Chord-half” Jiba/Jb Phonetic translation in Arabic Jaib Meaning “cove” or “bay” Sinus Latin word for “cove” or “bay” Sine: “the half-chord of the double of the central angle.” - “Where in the Sine is a Chord?” by Robert Rogers

  3. What Goes Where? Sine: “Half-chord” Cosine: “Complement’s sine” Tangent: “Tangere,” meaning “to touch” (Latin) Secant: “Secare” meaning “to cut” (Latin) Cotangent: Complements tangent Radius Cosecant: Complement of secant
