Sin (θ), Tan (θ), and 1 are the heights to the line starting from the x -axis, while Cos (θ), 1, and Cot (θ) are lengths along the x -axis starting from the origin. Since none of the six trigonometric functions are one-to-one, they must be restricted in order to have inverse functions.
26 lis 2024 · The inverse secant sec^(-1)z (Zwillinger 1995, p. 465), also denoted arcsecz (Abramowitz and Stegun 1972, p. 79; Harris and Stocker 1998, p. 315; Jeffrey 2000, p. 124), is the inverse function of the secant.
Wikipedia says "Some authors define the range of arcsecant to be (0 ≤ y <π/2 or π ≤ y <3π/2), because the tangent function is nonnegative on this domain." It is likely that your course adheres to this convention (and you are requested to comply). Trig functions are not invertible -- trig functions do not have inverses.
Sec Inverse x is the inverse trigonometric function of the secant function. Mathematically, it is denoted by sec -1 x. It can also be written as arcsec x. In a right-angled triangle, the secant function is given by the ratio of the hypotenuse and the base, that is, sec θ = Hypotenuse/Base = x (say).

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]
