Comment:

 While the plot doctests pass, in interactive Sage I get
 {{{
 sage: plot(sqrt(x^2-1), -2, 2)
 verbose 0 (2474: plot.py, generate_plot_points) WARNING: When plotting,
 failed to evaluate function at 100 points.
 verbose 0 (2474: plot.py, generate_plot_points) Last error message: 'math
 domain error'
 }}}
 before the plot.

 In the plot docs, "This reduces the possibility of, e.g., sampling sin
 only" please render sin via latex, or backticks.
