I Stationary field

    So, I got a question about stationary field.
    In the lecture the professor said, that our field is stationary, so we have [itex]\frac{du}{dt}=0[/itex], but from what I read in books, it only means, that [itex]\frac{\partial u}{\partial t} =0[/itex]. Who is right and why ?

    The total derivative makes no sense unless you have a function of ##t## only. A stationary field is a field that does not depend on ##t## and therefore ##\partial_t u = 0##.
