Quo facile dignoscatur quot futuræ sint Radices Affirmativæ, quot Negativæ, in Æquationibus ad Cosinus, hæc observetur Regula. Si fuerit \( n \) Numerus par, tot erunt Radices Affirmativæ quot Negativæ. Si fuerit \( n \) numerus impar, talis tamen ut \( \frac{n+1}{2} \), sit numerus par, numerus Affirmativarum erit \( \frac{n-1}{2} \), numerus Negativarum \( \frac{n+1}{2} \). Sin \( \frac{n+1}{2} \) fuerit numerus impar, numerus Affirmativarum erit \( \frac{n+1}{2} \), Negativarum \( \frac{n-1}{2} \). Aliqua huc spectantia jampridem inveneram, quæ Aëtis Philosophicis inserta fuerunt Anno 1707, deinde fusiæ fuerant exposita in Libro, qui inscribitur Miscellanea Analytica; sed cum ratio processus fuerit huic paulo dissimilis, nec fortasse adeo dilucida, nec directe ad eundem scopum collimans, hæc, spero, non inutilia judicabuntur.
