Trigonometric functions "Euler's formula", as well as near-modern abbreviations ("sin.", "cos.", "tang.", "cot.", "sec.", and "cosec."). A few functions were common historically, but are now seldom used, such as the chord (), the versine () (which appeared in the earliest tables), the coversine (), the haversine (), the exsecant (), and the excosecant (). See List of trigonometric identities for more relations between these functions. The word "sine" derives from Latin "sinus", meaning "bend; bay", and more specifically "the hanging fold of the upper part of a toga", "the bosom of a garment", which was chosen as the translation of what was
