we tracethedevelopment of themethod(1.1) by exhibiting and analyzingrelevantextracts
fromthepreserved notes,letters,and publications of Isaac Newton,JosephRaphson,and
ThomasSimpson.Muchof thesequenceof eventsrecounted hereis familiar

no claimsto originality.Ourpurposeis simplyto providea comprehensive accountof the
historical
rootsoftheubiquitous process(1.1), assembling a number ofpreviouslypublished

Newton'soriginalpresentation of his method,contrastingthiswiththecurrent formulation
