Secant and Cosecant - Algebrica The secant and cosecant of an angle θ are defined as the reciprocals of cos (θ) and sin (θ), extending trigonometric relationships
Cosecant - Math Open Reference In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side In a formula, it is abbreviated to just 'csc'
Secant, Cosecant, and Cotangent Functions - CK-12 Foundation They are the reciprocals of sine, cosine and tangent If sin A = a c, then the definition of cosecant, or csc, is csc A = c a If cos A = b c, then the definition of secant, or sec, is sec A = c b If tan A = a b, then the definition of cotangent, or cot, is cot A = b a
Cosecant Definition (Illustrated Mathematics Dictionary) In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle The abbreviation is csc csc θ = hypotenuse opposite It is not commonly used, and is equal to 1 sine
