| Abstract: | The vector analysis holds the extremely important status in the electrodynamics and the correlative discipline,but we often neglect the partial derivative of the unit vector when we carry on the vector analysis,thus obtain the wrong result.This article which points out the importance of the partial derivative of the unit vector through the common mistakes in the vector analysis and carries on the analysis of the practical examples enables the general scholars to have a comprehensive understanding to this question. |
