D In the case of the cuspidal cubic the point (0, 0) is a cusp, in the case of the
crunodal cubic the point (0,0) is a double point, and in the case of the acnodal
cubic the point (0, 0) is an isolated point of the curve: these are three of the types
of ...

The History and Development of Nomography
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 ...

... the nonsingular cubic curves (simplex and complex in Cayley's terminology),
the nodal curves (acnodal and crunodal), and the cuspidal class. Classification
was the motivation for much of Cayley's geometrical work and cubic curves

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

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 ...

We have herein a better principle of classification; 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 ...
