Clavis geometrica catholica. The geometrical key: or the gate of equations unlock'd: a new discovery of the construction of all equations ... not exceeding the fourth degree; viz. of, linears, quadratics, cubics, biquadratics; and the finding of all their roots ... without the use of mesolable, trisection of angles; without reduction, depression, or any other previous preparation of equations, by a circle, and any ... parabole. And this, by one only general rule ... Fortified with demonstrations / [Thomas Baker].
Baker, Thomas, 1624 or 1625-1690 | Date: 1684
