Apr 28, 2017 · The equation y = cos − 1 (x) defines the inverse cosine function, which gives the angle whose cosine equals x. Its domain is the interval [-1, 1], and the range is [0, π]. As x increases, y decreases, making it a monotonically decreasing function.

Oct 31, 2023 · Find the domain of the function y = cos-1 (|x - 1|). Show your steps. Since the domain of inverse of cosine function is [-1, 1], finds the domain of the given function as follows: -1 ≤ x - 1 ≤ 1. So, 0 ≤ x ≤ 2. And, -1 ≤ 1 - x ≤ 1. => 1 ≥ x - 1 ≥ -1. So, 2 ≥ x ≥ 0. Concludes the domain of cos-1 (|x - 1|) as [0, 2].

How do you graph and list the amplitude, period, phase shift for y =cos2x−1 ? As below. Explanation: Standard form of cosine function is y = Acos(Bx−C)+D y = cos2x−1 A = 1,B = 1,C = 0,D = −1 ...

Inverse cosine is an important inverse trigonometric function. Mathematically, it is written as cos -1 (x) and is the inverse function of the trigonometric function cosine, cos (x). An important thing to note is that inverse cosine is not the reciprocal of cos x.
