You can use it as long as you don't include 0 in the search
interval. find_root is a bit picky about its first argument. I'm not
sure why.
(%i25) %o15;
3.588
atan(-----)
fl
6096 tan(-----------)
1632
(%o25) ---------------------
%pi
tan(-----)
10800
(%i26) find_root(''%o15-6096,fl,0.1,20);
(%o26) 6.98149293282488
the '' in find_root is required because otherwise find_root has
trouble handling the expression. '' causes the expression to be
evaluated before find_root gets ahold of it...
For the group: have we fixed or improved find_root with respect to its
first argument since my version of maxima (at work)??? (5.10.0)
