It accepts an array as input and returns a new array containing the arccosine values. Examples demonstrate its use with -1, 0, and 1, resulting in outputs of π, π/2, and 0 respectively. The examples also showcase plotting the function, with `x` values between -1 and 1 and corresponding `acos(x)` outputs.\n"]]
