WebThe reciprocal of sine, cos, and tan are cosecant (csc), secant (sec), and cotangent (cot) respectively. The formula of each of these functions are given as: Sec a = 1/ (cos a) = Hypotenuse/Adjacent = CA/AB Cosec a = 1/ (sin a) = Hypotenuse/Opposite = CA/CB cot a = 1/ (tan a) = Adjacent/Opposite = BA/CB WebConventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent.
