**node**, or when it is secondly at the**node**, any peculiarity in the motion; the singularity consists in the point coming twice into the same position; and so in (4) the singularity is in the line coming twice into the same position. - The curve (1 x, y, z) m = o, or general curve of the order m, has double tangents and inflections; (2) presents itself as a singularity, for the equations dx(* x, y, z) m =o, d y (*r x, y, z)m=o, d z(* x, y, z) m =o, implying y, z) m = o, are not in general satisfied by any values (a, b, c) whatever of (x, y, z), but if such values exist, then the point (a, b, c) is a
**node**or double point; and (I) presents itself as a further singularity or sub-case of (2), a cusp being a double point for which the two tangents becomes coincident. - The expression 2 is that of the number of the disposable constants in a curve of the order m with
and cusps (in fact that there shall be a**nodes****node**is I condition, a cusp 2 conditions) and the equation (9) thus expresses that the curve and its reciprocal contain each of them the same number of disposable constants. - 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. - But, as is evident, the
**node**or cusp is not a point of contact of a proper tangent from the arbitrary point; we have, therefore, for a**node**a diminution and for a cusp a diminution 3, in the number of the intersections; and thus, for a curve with 6and K cusps, there is a diminution 26+3K, and the value of n is n= m (m - I)-26-3K.**nodes** - But if the given curve has a
**node**, then not only the Hessian passes through the**node**, but it has there a**node**the two branches at which touch respectively the two branches of the curve; and the**node**thus counts as six intersections; so if the curve has a cusp, then the Hessian not only passes through the cusp, but it has there a cusp through which it again passes, that is, there is a cuspidal branch touching the cuspidal branch of the curve, and besides a simple branch passing through the cusp, and hence the cusp counts as eight intersections. - The
**node**or cusp is not an inflection, and we have thus for a**node**a diminution 6, and for a cusp a diminution 8, in the number of the intersections; hence for a curve with 6and cusps, the diminution is = 66+8K, and the number of inflections is c= 3m(m - 2) - 66 - 8K.**nodes** - 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 ofand cusps is greater than unity.**nodes** - Hence, in the case of a curve which has 6
and K cusps, the apparent diminution 2(m 2 - m-6)(26+3K) is too great, and it has in fact to be diminished by 2 1(25(5 - I) +66K+ 2 K(K - I)1, or the half thereof is 4 for each pair of**nodes**, 6 for each combination of a**nodes****node**and cusp, and 9 for each pair of cusps. - By means of Pliicker's equations we may form a table - The table is arranged according to the value of in; and we have m=o, n= r, the point; m =1, n =o, the line; m=2, n=2, the conic; of m = 3, the cubic, there are three cases, the class being 6, 4 or 3, according as the curve is without singularities, or as it has 1
**node**or r cusp; and so of m =4, the quartic, there are ten cases, where observe that in two of them the class is = 6, - the reduction of class arising from two cusps or else from three.**nodes** - A property independent of the particular axes of co-ordinates used in the representation of the curve by its equation; for instance, the curve may have a
**node**, and in order to this, a relation, say A = o, must exist between the coefficients of the equation; supposing the axes of co-ordinates altered, so that the equation becomes u' = o, and writing A' = o for the relation between the new coefficients, then the relations A = o, A' = o, as two different expressions of the same geometrical property, must each of them imply the other; this can only be the case when A, A' are functions differing only by a constant factor, or say, when A is an invariant of u. - Similarly a cubic through the two circular points is termed a circular cubic; a quartic through the two points is termed a circular quartic, and if it passes twice through each of them, that is, has each of them for a
**node**, it is termed a bicircular quartic. Such a quartic is of course binodal (m = 4, 6= 2, K = o); it has not in general, but it may have, a third**node**or a cusp. Or again, we may have a quartic curve having a cusp at each of the circular points: such a curve is a " Cartesian," it being a complete definition of the Cartesian to say that it is a bicuspidal quartic curve (m= 4, 6 = o, K= 2), having a cusp at each of the circular points. - .,, a given
