Try the exclude optional argument to plot to tell sage to ignore specific points not in the domain of the function, e.g.
plot(arcsec(x), (x,-8,8), exclude=[-1,1])Note that this option technically just excludes the poles at x=-1 and x=1 but Sage gracefully ignores the points in between which are not in the domain.
