PARABOLA, (parabole, Fr.) in geo-metry, a figure arising from the sectionof the cone, when cut by a plane paral-lel to one of its sides.

From the same points of a cone, there-fore, only one parabola can be drawn ;all the other sections, within these paral-lels, being ellipses, and all without, hy-perbolas.

Properties of the Parabola. Thesquare of an ordinate is equal to therectangle of the abscissa, and four timesthe distance of the focus from the ver-tex.

The perpendicular on the tangent,from the focus, is a mean proportionalbetween the distance from the vertex tothe focus, and the distance of the focusfrom the point of contact.

All lines within the parabola, whichare drawn parallel to the axis, are calleddiameters.

The parameter of any diameter is aright line, of such a nature, that the pro-duct under the same, and the abscissa,are equal to the square of the semi-or-dinate.

The squares of all ordinates to thesame diameter, are to one another astheir abscissas.

Cartesian Parabola is a curve ofthe second order, expressed by the equa-tion ri/ “ ax 5 -f- bx 2 -f- ( .i -f- </. con-taining four infinite legs, being the 66th\ G 2
