The arccosine perform, denoted as arccos(x), is the inverse perform of the cosine perform. It provides the angle whose cosine is x. The area of the arccosine perform is [-1, 1] and its vary is [0, ].
The graph of the arccosine perform is a curve that begins on the level (-1, ) and ends on the level (1, 0). The curve is symmetric concerning the y-axis.
