A rod of length `l` with thermally insulated lateral surface is made of a material whose thermal conductivity varies as `K=sc//T` where `c` is a constant. The ends are kept at temperatures `T_(1)` and `T_(2)`. Find the temperature at a distance `x` from te first end where the temperature is `T_(1)` and the heat flow density.
