Classification

Examples
- The graph of the cosine function intersects the x-axis at π/2, so the arccosine of any number in the interval [-1,0) yields π/2.
- In a trigonometry test, she struggled to remember that the range of the arccosine function lies within the interval [0,π].
- When studying circular functions in class, she came across the definition of arccosine as the angle that has a cosine equal to a given number.
- If a machine produces waveforms of arccosine x that all yield different curves due to changes in input.
- On plotting arccosine 1 and observing the y-value approaching π in an exponential curve pattern that reverses.
