Abstract

By using the differential geometry，the vector limit and the relationship of various coordinate systems，we deduce the spatial derivatives of unit vectors in common curvilinear coordinates. This derivation method is simple and intuitive，which is easy to understand and apply in physics teaching and practice.

Key words： unit vectors; differential geometry; curvilinear coordinate; spatial derivative
