The whole-partial derivative
We discuss two types of partial derivatives which occur, e.g., in the Euler–Lagrange equations. To avoid confusion, a different notation (ðF/ðx μ ) and a new name (whole-partial derivative) are suggested for what is usually written as ∂F/∂x μ but acts on both the explicit and implicit dependence of...

| Zusammenfassung: | We discuss two types of partial derivatives which occur, e.g., in the Euler–Lagrange equations. To avoid confusion, a different notation
(ðF/ðx
μ
)
and a new name (whole-partial derivative) are suggested for what is usually written as
∂F/∂x
μ
but acts on both the explicit and implicit dependence of F upon the coordinate
x
μ
