A rod of length l with thermally insulated lateral surface consists of material whose heat conductivity coefficient varies with temperature as `k= a//T`, where a is a constant. The ends of the rod are kept at temperatures `T_1 and T_2`. Find the function T(x), where x is the distance from the end whose temperature is `T_1`.
