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]
