General heat conduction equation of spherical coordinate system , Derivation

By the help of this lecture, one can easily understand i.e. how to derive the general heat conduction equation for spherical co-ordinate system. In general, the heat transfer within a solid sphere at a point can be in radial, tangential (vertical plane) and tangential (Horizontal plane).. The temperature profile with respect to three corresponding directions has been derived in an easy way.
