There is a package by Ted Ersek named RootSearch on MathSource that may
solve your problem and be more convenient to use. I believe that it finds
all roots and returns them in order.

Hi,

 I'm trying to find roots of the constitutive equation of a
liquid crystal-polymer mixture model. There are multiple roots of the
equation and I used FindRoot to find them. The sequence of roots is very
important in my calculations.

 Is there any routine or a clever way to (numerically) find all the
roots of an equation in a predefined values?

 As it is now I have to look for each individual root manually and it
gets a bit tedious as the number of required modes increases.

I will appreciate your help.
