Wolf. In "M�chanique Analytique" Lagrange reformulated classical Newtonian mechanics in a purely analytical manner whereas Newton derived his results geometrically or synthetically with the aid of figures. <br><br>"Lagrange proposed to reduce the theory of mechanics and the art of solving problems in that field to general formulas the mere development of which would yield all the equations necessary for the solution of every problem." DSB. In his preface Lagrange draws attention to the absence of diagrams in the book which he believed the lucidity of his own presentation had rendered superfluous. <br><br>Horblit/Grolier 61; Dibner 112; Sparrow 120; Norman 1257. hardcover
