**geometrically**as actually described, or kinematically as in the course of description by the motion of a point; in the former point of view, it is the locus of all the points which satisfy a given condition; in the latter, it is the locus of a point moving subject to a given condition.But it can be shown, analytically or

**geometrically**, that if the given curve has a node, the first polar passes through this node, which therefore counts as two intersections, and that if the curve has a cusp, the first polar passes through the cusp, touching the curve there, and hence the cusp counts as three intersections.AdvertisementSecondly, as to the inflections, the process is a similar one; it can be shown that the inflections are the intersections of the curve by a derivative curve called (after Ludwig Otto Hesse who first considered it) the Hessian, defined

**geometrically**as the locus of a point such that its conic polar (§ 8 below) in regard to the curve breaks up into a pair of lines, and which has an equation H = o, where H is the determinant formed with the second differential coefficients of u in regard to the variables (x, y, z); H= o is thus a curve of the order 3 (m - 2), and the number of inflections is =3m(m-2).The power and spirit of the analytic method will be appreciated by showing how it expresses the relations of motion as they were conceived

**geometrically**by Newton and Kepler.Having these data, the position of the planet at any other time may be

**geometrically**the dogmas defined in the Creed.The Aziz version is a post-modern deconstructed

**geometrically**arranged stuffed eggplant dish made with halved baby eggplants.AdvertisementIt is often impossible to observe the pressure-coefficient dp/de directly, but it may be deduced from the isothermal compressibility by means of the

**geometrically**obvious relation, BE = (BEÃƒâ€ C) XEC. The ratio BEÃƒâ€ C of the diminution of pressure to the increase of volume at constant temperature, or - dp/dv, is readily observed.It was especially used to represent

**geometrically**the periodic apparent retrograde motion of the outer planets, Mars, Jupiter and Saturn, which we now know to be due to the annual revolution of the earth around the sun, but which in the Ptolemaic astronomy were taken to be real.Finials are

**geometrically**shaped or the rods have end caps.There is no linear covariant, since it is impossible to form a symbolic product which will contain x once and at the same time appertain to a quadratic. (v.) is the Jacobian;

**geometrically**it denotes the bisectors of the angles between the lines ax, or, as we may say, the common harmonic conjugates of the lines and the lines x x .He solved quadratic equations both

**geometrically**and algebraically, and also equations of the form x 2 "+ax n +b=o; he also proved certain relations between the sum of the first n natural numbers, and the sums of their squares and cubes.AdvertisementCubic equations were solved

**geometrically**by determining the intersections of conic sections.The method of solving equations

**geometrically**was considerably developed by Omar Khayyam of Khorassan, who flourished in the 1 r th century.By applying the method of the differential calculus, we obtain cos i= { (µ 2 - 1)/(n24-2n)} as the required value; it may be readily shown either

**geometrically**or analytically that this is a minimum.It is often impossible to observe the pressure-coefficient dp/de directly, but it may be deduced from the isothermal compressibility by means of the

**geometrically**obvious relation, BE = (BEÃ†C) XEC. The ratio BEÃ†C of the diminution of pressure to the increase of volume at constant temperature, or - dp/dv, is readily observed.This is

**geometrically**obvious from the form of the area representing the function on the indicator diagram, and also follows directly from the first law.AdvertisementHis method of estimating the relative lunar and solar distances is

**geometrically**correct, though the instrumental means at his command rendered his data erroneous.The circle, for instance, is regarded

**geometrically**as a line described in a particular way, while from the point of view of mensuration it is a figure of a particular shape.Although Hippocrates could not determine the proportionals, his statement of the problem in this form was a great advance, for it was perceived that the problem of trisecting an angle was reducible to a similar form which, in the language of algebraic geometry, is to solve

**geometrically**a cubic equation.Beside the equivalence of the hon to 5 utens weight of water, the mathematical papyrus (35) gives 5 besha = (2/3)cubic cubit (Revillout's interpretation of this as 1 cubit cubed is impossible

**geometrically**; see Rev. Eg., 1881, for data); this is very concordant, but it is very unlikely for 3 to be introduced in an Egyptian derivation, and probably therefore only a working equivalent.Pappus gives several solutions of this problem, including a method of making successive approximations to the solution, the significance of which he apparently failed to appreciate; he adds his own solution of the more general problem of finding

**geometrically**the side of a cube whose content is in any given ratio to that of a given one.AdvertisementWhile there he sent several papers, in which some questions of navigation were treated

**geometrically**, to Gaspard Monge, at that time minister of marine, through whose influence he obtained an appointment in Paris.In the Theorie nouvelle de la rotation des corps (1834) he treats the motion of a 'rigid body

**geometrically**, and shows that the most general motion of such a body can be represented at any instant by a rotation about an axis combined with a translation parallel to this axis, and that any motion of a body of which one point is fixed may be produced by the rolling of a cone fixed in the body on a cone fixed in space.An infinitely small rotation about any axis is conveniently represented

**geometrically**by a length AB measures along the axis and proportional to the angle of rotation, with the convention that the direction from A to B shall be related to the rotation as is the direction of translation to that of rotation in a righthanded screw.Thirdly, for the double tangents; the points of contact of these are obtained as the intersections of the curve by a curve II = o, which has not as yet been

**geometrically**defined, but which is found analytically to be of the order (m-2) (m 2 -9); the number of intersections is thus = m(rn - 2) (m 2 - 9); but if the given curve has a node then there is a diminution =4(m2 - m-6), and if it has a cusp then there is a diminution =6(m2 - m-6), where, however, it is to be noticed that the factor (m2 - m-6) is in the case of a curve having only a node or only a cusp the number of the tangents which can be drawn from the node or cusp to the curve, and is used as denoting the number of these tangents, and ceases to be the correct expression if the number of nodes and cusps is greater than unity.The angle cp is termed the eccentric angle, and is

**geometrically**represented as the angle between the axis of x (the major axis of the ellipse) and the radius of a point on the auxiliary circle which has the same abscissa as the point on the ellipse.But Buteo and Kircher have proved

**geometrically**that, taking the cubit of a foot and a half, the ark was abundantly sufficient for all the animals supposed to be lodged in it.For instance, those of a ternary form involve two classes which may be

**geometrically**interpreted as point and line co-ordinates in a plane; those of a quaternary form involve three classes which may be**geometrically**interpreted as point, line and plane coordinates in space.
