Syntagma mathesios : Containing the resolution of equations: with a new way of solving cubic and biquadratic equations, analytically and geometrically. Also the universal method of converging series, after an easy and expeditious manner. Wherein also are treated the series for trigonometrical operations; some new useful properties of conics; centre of oscillations; the direct and inverse method of the laws of centripetal forces; a variety of exponential equations; with the investigation of several other abstruse problems, &c. To all which is prefixed, an essay on the mathematics.
