SUMMARY
The del operator in cylindrical coordinates is defined with an upper notation due to the nature of unit vectors that change with position, resulting in the inclusion of a 1/r term. This arises from the relationship between angular displacement and linear distance in the eθ direction, where distance is expressed as r times the angle. For a comprehensive understanding, refer to "Engineering Electromagnetics" by Nathan Ida, which provides a detailed derivation starting on page 80. Additionally, discussions by forum members arildno and HallsOfIvy further elucidate this topic.
