A student just pointed out to me that the asymptote at x=1 is drawn
in the following plot only when k is odd. For even values, no
asymptote appears.
Plot[1/(x - 1)^k, {x, -5, 5}, PlotRange -> {{-5, 5}, {-5, 5}},
Exclusions -> {x - 1 == 0}, ExclusionsStyle -> {{Thick, Red}}]
This appears to generalize to other examples like Tan[x]^k.
Anyone know why?
