Si calculum per logarithmos hyperbolicos exsequi constitutum est, quantitateauxiliari F vti praestat, quae per aequ. III determinabitur, atque inde N per XI;semiparameter e radio vectore, vel vicissim hic ex illo per formulam VIII compu-tabitur; jiars secunda ipsius N duplici si lubet modo erui potest, scilicet per for-mulam log liyp tang ( 45 ° + ~F), et per hanc log hyp cos | (v —w) — log hyp cos | {v+ip)-

Ceterum patet, quantitatem N hic vbiquam si logarithmi Briggici adhibeantur.
