To quickly assess the difficulty of the text, read a short excerpt:
As the equation is p. 429 z=px+qy+f(p,q), the subsidiary equations are dp _dq _ !T - ~0~ _ " - " Two integrals are p = a, q = b, each consistent with the original equation, and also consistent with one another (§ 208). Elimi- nating p and q, we have z — ax + by +f(a, b). Ex. 4. The subsidiary equations are dp _dq _ P ~ a ~"\ so we can take p = aq as an integral. Using this, we have q(ax+y) = q n f(a, 1), i .
