See Socratic graph, for sin x / sin x.
Explanation:
graph{sinx/sinx [-10, 10, -5, 5]}
Analytically, f(x)/f(x) has holes at the zeros of f(x).
The holes are 0-space points. How could the graph depict the
holes? The holes have no dimensions.
Here, sans zeros #x = kpi, k = 0, +-1, +-2, +-3, .... at which the form is
indeterminate
sinx/sinx=1
