Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle.Secant FunctionSecant function is defined as the ratio of the hypotenuse and the adjacent side of the angle in a right-angled triangle. It is the reciprocal of the ...
Usingtrigonometry formula, the value of sec 70° can be given in terms of other trigonometric functions as: ± 1/√(1-sin²(70°)) ±√(1 + tan²(70°)) ±√(1 + cot²(70°))/cot 70° ± cosec 70°/√(cosec²(70°) - 1) ...
