At this point I find find_root(''p, x, 0, 4) finds a root at about 3.14.
find_root evaluates its first argument in manner different from
other Maxima functions, so the quote-quote is needed.
Also, if the first argument is an expression, you have to specify
the independent variable.
I have reworked find_root to make it evaluate its first argument
in same way as other Maxima functions; more on that soon.
