I would like to store the root/solution obtained by the FindRoot[] function to a variable. How can I do that?
Thanks!

Hi, Nansheng,
Assume this:
eq=x^2-x-1==0;
is your equation, and this:
FindRoot[eq, {x, 1}]
{x -> 1.61803}
is what FindRoot returns you. Then you may simply do the following:
y = FindRoot[eq, {x, 1}][[1, 2]];
y
1.61803
Is this the thing you had in mind?
Have fun, Alexei
