The general heat conduction equation in any co-ordinate system, tell the temperature profile with respect to space. While deriving the heat conduction equation in spherical co-ordinate system, sometimes it becomes difficult to imagine the geometric figure of the small elemental part of the sphere. By the help of this lecture one can easily learn that. Once it is learnt i.e., how to draw the elemental part of sphere, the derivation becomes easy. Derivation is described in my continued next lecture...
