    assuming that V is actually molar volume... V/n

    (du/dV) at constant T is

    T (dP/dT) at constant V, minus P

    = RT/(V - b) - RT/(V - b) 

    = zero.

    So it seems (dV/du) at constant T would be infinite.

    Because really you can't change u without changing T.

    The van der Waals equation (or van der Waals equation of state; named after Johannes Diderik van der Waals) is an equation of state that generalizes the ideal gas law based on plausible reasons that real gases do not act ideally

    P(V-b)=RT
