## Homework Statement

Hi

Say I have a function [itex]f(x(t), t)[/itex]. I am not 100% sure of the difference between

[tex]

\frac{df}{dt}

[/tex]

and

[tex]

\frac{\partial f}{\partial t}

[/tex]

Is it correct that the relation between these two is (from the chain rule)

[tex]

\frac{df}{dt} = \frac{\partial f}{\partial t} + \frac{\partial f}{\partial x}\frac{dx}{dt}

[/tex]
