In Response To 'Re: Re: Solve equation(s) with a List as Variable'
From In:= FindRoot::lstol: The line search decreased the step size to within tolerance specified by AccuracyGoal and PrecisionGoal but was unable to find a sufficient decrease in the merit function. You may need more than MachinePrecision digits of working precision to meet these tolerances.
Without the exact numbers for a particular example I'm sort of left with "I typed some stuff in, some stuff came out, some stuff is wrong, what do I do?"
If I just the FindRoot wrapped around the Map, replace the 0.005 with 5/1000 and simplify then I get expressions like
200000*(37/100000000000000 + Pi/500000000000000) - x*Tanh[37/(500000000*x)]
It isn't clear to me if there are zeros of that.
