WebSo we can say: tan (θ) = sin (θ) cos (θ) That is our first Trigonometric Identity. Cosecant, Secant and Cotangent We can also divide "the other way around" (such as Adjacent/Opposite instead of Opposite/Adjacent ): Example: when Opposite = 2 and Hypotenuse = 4 then sin (θ) = 2/4, and csc (θ) = 4/2 Because of all that we can say: sin (θ) = 1/csc (θ)
