... a function V of x, y, z, then H (as a letter not otherwise explained) denotes a ... r and considering it as a given function, H = const.will be a partial differential equation containing the constant H.For instance, if H denote the function pqr -xyz, H = const.is the partial differential equation, pqrxyz = H (a given constant).The integration of the partial differential equation, H = const., depends upon that of the linear partial differential equation (H, Θ) = 0, where as usual (Η, Θ) signifies ... two conjugate solutions a, b of the equation (H, Θ) = 0, viz.a, b as solutions are ...
