=> [with patch, positive review] Create
plot_slope_field function
Comment:
This and #4103 apply to 3.1.2 and pass sage -testall. It does a great job
and is a very valuable addition.
A question for possibly a future patch: it will not plot
{{{
plot_slope_field(x/y, (x,-3,3), (y,-3,3)).show(aspect_ratio=1)
}}}
because of the problem at y=0. However, should it? A slope of plus or
minus infinity has a well-defined meaning. Should one try to trap
singularities like that and just plot them as vertical direction fields in
the future?
Anyway, thanks Jason for this nice addition! This will be very useful for
teaching differential equations.
