That is, the rhamphoid cusp on r is special if and only if n3 = 3An2. An analogous
discussion then proves that the latter equation holds if and only if n5 = a'n2 + l(
Un4, for some a'. That is, the rhamphoid cusp on the dual curve n is ordinary or ...

The object of the following exercises is to show that no such local diffeomorphism
<f> exists, and to draw a distinction between ordinary and rhamphoid cusps - two
orders of nastiness for cusped curves. In the remainder of the section we get ...

Note the different shapes of these cusps depending on the different limiting radii
of curvature, and on whether or not the cusp is rhamphoid. Exercises 8.12. For
each of the following curves, show that there is a cusp at the origin, and classify
the ...

Rhamphoid Cuspidal Curves. 26. By pursuing a method similar to that employed
in the case of a cuspidal curve, it can be shown that the equation of a surface
possessing a rhamphoid cuspidal carve is S'U._u+2a*SV„_t+O>Wn_t=0 (4»), ...

has the form of the cusp of the second species, or rhamphoid cusp. There is an
apparent inflexion at the rhamphoid cusp, because, if a person describing the
curve continuously passes through the cusp, the concavity of the curve is to his
right ...

The solution 4q = N' leads to a triple point consisting of a branch which passes
through a rhamphoid cusp, and its constituents are 8=3, « = 1, t = 1, i=l. When q =
N= 0, the branch touohes the cuspidal tangent, but the curve is now of the form ...
