The following question is a logical continuation of this one. The Ted Ersek's RootSearch package doesn't work with this code:
Needs["Ersek`RootSearch`"];
Quiet@RootSearch[τ - ArcCos[1/(-11.` + 6.16949` E^(0.05` τ))]/
Sqrt[0.380626` + (0.08062600000000003` - 0.04130349999999999` E^(0.05` τ))/
(-1.` + 1.` E^(0.05` τ) - 0.25` E^(0.1` τ))] == 0, {τ, -5, 14}]
with error message:
Get::noopen: Cannot open Ersek`RootSearch`. >>
Needs::nocont: Context Ersek`RootSearch` was not created when Needs was evaluated. >>
Thank's for help!
