3.3 An acnodal cubic Although the algebraic equation of the acnodal cubic curve
is similar to that of the crunodal cubic, its shape is quite different. The curve has
an acnode, or isolated point, at the origin. Again the curve resembles the ...

If ∆ > 0 the curve is crunodal, if ∆ = 0 it is cuspidal and if ∆ < 0 it is acnodal. These
points can be illustrated with reference to three examples given in the section on
Clark's work. 3.5.1. Crunodal Form. f1f2f3 − 1 = 0 which produced the folium of ...

J. E. Wright (***) constructs the nodal cubics through eight given points and
discusses their reality. If all basis points are real, not more than two acnodal
cubics are in the pencil. In general R—\ = C— A. £ = number real basis points, C
= number ...

__ _±_ _ Z2 1/3 2/3 It is an elementary but lengthy procedure to show that: (i) an
acnodal curve of the pencil/,=0 has at most four real inflexions, (ii) a crunodal
curve corresponding to a value of e such that — 4<e< — 16/9 has at least four
real ...

The oval may unite itself with the infinite branch, or it may dwindle into a point,
and we have the crunodal and the acnodal forms respectively ; or if
simultaneously the oval dwindles into a point and unites itself to the infinite
branch, we have the ...

\Ve have herein a better principle of classificition; considering cubic curves, in the
first instance, according to singularities, the curves are non-singular, nodal (viz.,
crunodal or acnodal), or cuspidal ; and we see further that there are two kinds of ...

... x = —^- '— and The fact that the acnodal cubic has three real inflexions is well
known and may be easily demonstrated, either by means of Klein's equation for
real, plane, algebraic curves [1], or by considering the discriminant of (3). Hence

There are the two real nodal lines (_1/=0, .1:=-y) and (z=0, .r='y'), each of these
being in the neighbourhood of the axis crunodal, and beyond certain limits
acnodal; the surface is a scroll, being, in fact, the well-known surface which is the
