Help! I'm trying to use Sage to plot x-intercepts, and there seems to be a problem when I try to zoom in too far. E.g. if I execute


then I get exactly what I expect, but if I execute


then I get this error message:

Traceback (click to the left of this block for traceback) ... Unknown symbol: \verb (at char 0), (line:1, col:1)

Curiously, this seems to be directly related to the fact that my function is crossing the x axis on the domain in question. E.g. if I try


then everything comes out fine.

Any thoughts on what's going on and/or how to get around it?

How can I get precise tick marks? E.g if I execute


then ALL of the tick marks on the x axis read 7.071e-1. How can I get the tick marks to write out to seven decimal places? I've tried messing around with the ticks and tick_formatter specifications, but I get either no improvement or an error message.

Can anyone help? Thanks.
