See graph and my idiosyncratic explanation.

#### Explanation:

Conventionally limited ( for trigonometric arccos )

See the truncated-graph, with asymptote

the limiting lines

graph{(y-arccos(1/x))(y-pi/2)(y-pi)(y)=0}

See the wholesome-inverse graph for

using the inverse

graph{(x cos y - 1)(x^2-0.25) = 0[-50 50 -25 25]}

You can see the effect of the small operator

great

Observe in both the graphs that

Please note, that piecewise/wholesome,
