# XXXVI. A disquisition concerning certain fluents, which are assignable by the arcs of the conic sections; wherein are investigated some new and useful theorems for computing such fluents

@article{LandenXXXVIAD, title={XXXVI. A disquisition concerning certain fluents, which are assignable by the arcs of the conic sections; wherein are investigated some new and useful theorems for computing such fluents}, author={John Landen}, journal={Philosophical Transactions of the Royal Society of London}, pages={298 - 309} }

Mr. Mac Laurin, in his Treatise of Fluxions, has given sundry very elegant theorems for computing the fluents of certain fluxions by means of elliptic and hyperbolic arcs; and Mr. D'Alembert, in the memoirs of the Berlin Academy, has made some improvement upon what had been before written on that subject, but some of the theorems given by those gentlemen being in part expressed by the difference between an arc of an hyperbola and its tangent, and such difference being not directly attainable… Expand
