Total vs partial time derivative of action
Total vs partial time derivative of action - Physics Stack Exchange
From the definition of the action, its total time derivative along the path is dS/dt=L.
What is the actual difference between total and partial derivatives?
A partial derivative only tells you how an equation for that physical quantity depends explicitly on time. If all your parameters in an equation ...
What exactly is the difference between a derivative and a total ...
Total derivative is a measure of the change of all variables, while Partial derivative is a measure of the change of a particular variable ...
Can you explain the difference between a total time derivative and ...
In summary, the key difference is that the total time derivative accounts for changes in both time and space, while the ordinary time derivative ...
Unlike partial derivatives, the total derivative approximates the function with respect to all of its arguments, not just a single one. In many situations ...

Well, in this case the difference is easy: The partial derivative is expected to use sensible notation, whereas the total derivative somehow ...
Partial or total derivative in Faraday's law - Physics Forums
In the differential form, the partial time derivative is written, while in the integral form, it is simply the time derivative. The integral ...
What is the difference between a partial derivative and total derivative?
Partial derivatives are the measure of change in a function with respect to change in a single variable, while taking all other variables as constant. However, ...
Commutativity of partial and total derivative - Physics Forums
So it is meaningful to consider the partial derivatives of f wrt these coordinates. The total derivative, d/dt, is only meaningful for some ...
Total vs partial derivatives - GitHub Pages
Partial derivatives involve only individual components. Total derivatives are the derivatives of an objective or constraint with respect to design variables.
