Where is the minus sign whe must obtain in the second case??
> Solve[(E^c)^2 - A*E^c + 1 == 0, c]
{{c -> Log[(1/2)*(A - Sqrt[-4 + A^2])]},
{c -> Log[(1/2)*(A + Sqrt[-4 + A^2])]}}
> Solve[(E^(-c))^2 - A*E^(-c) + 1 == 0, c]
{{c -> Log[(1/2)*(A - Sqrt[-4 + A^2])]},
{c -> Log[(1/2)*(A + Sqrt[-4 + A^2])]}}
