These properties apply to all the inverse trigonometric functions. The principal inverses are listed in the following table. Note: Some authors [citation needed] define the range of arcsecant to be , because the tangent function is nonnegative on this domain. This makes some computations more consistent.
The range of arcsecant: y∈ [0; π/2)∪ ( π/2; π]. Arcsecant is a non-periodic function. The arcsecant increases and is continuous on the interval x∈ (-∞; -1] and x∈ [1, + ∞), since the secant function (x= secy) is strictly increasing and continuous in the intervals [0; π/2) and (π/2;π]
For a similar reason, the same authors define the range of arccosecant to be ( - π < y ≤ - π /2 or 0 < y ≤ π /2 ).) If x is allowed to be a complex number , then the range of y applies only to its real part. Relationships between trigonometric functions and inverse trigonometric functions
12 sie 2024 · Theorem: Properties of the Arcsecant and Arccosecant Functions. Properties of \(f(x)= \mathrm{arcsec}(x)\) \(\sec^{-1}\left( x \right) = \theta\) if and only if \(\sec\left( \theta \right) = x\) where \(\theta \in \left[ 0,\frac{\pi}{2} \right) \cup \left( \frac{\pi}{2}, \pi \right]\)
15 cze 2021 · We first consider \ (f (x) = \cos (x)\). Choosing the interval \ ( [0,\pi]\) allows us to keep the range as \ ( [-1,1]\) as well as the properties of being smooth and continuous. Recall from Section \ref {InverseFunctions} that the inverse of a function \ (f\) is typically denoted \ (f^ {-1}\).
Arcsecant function is the inverse of the secant function denoted by sec -1x. It is represented in the graph as shown below: Therefore, the inverse of secant function can be expressed as; y = sec-1x (arcsecant x) Domain & Range of Arcsecant: What is arccosecant (arccsc x) function?
