12 gru 2022 · sin(− θ) = − sinθ sin (− θ) = − sin θ. cos(− θ) = cosθ cos (− θ) = cos θ. cot(− θ) = − cotθ cot (− θ) = − cot θ. csc(− θ) = − cscθ csc (− θ) = − csc θ. sec(− θ) = secθ sec (− θ) = sec θ. The Reciprocal Identities define reciprocals of the trigonometric functions. sinθ = 1 cscθ sin θ = 1 csc θ.
