Webtan (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) to get: Cosecant Function: csc (θ) = Hypotenuse / Opposite. Secant Function: sec (θ) = Hypotenuse / Adjacent.
