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. Cotangent Function: cot (θ) = Adjacent / Opposite.
$\cos(x)^2$ can be understood as $\cos x^2 = \cos(x^2)$ $\cos^2 x$ or $\cos^2 (x)$ can also mean $\cos(\cos(x))$. If you want to use this notation, you should note it, because it is less common.
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are ...
