NEPHROID The nephroid is a kidney-shaped curve defined by x = fl(3cos(9)-cos(
39)), y = a(3sin(9)-sin(39)) The graph of Figure 2.47 is created from the deltoid
model of Figure 2.45 by setting the parameters a = b=\,e = g = -\ and d =/= c = 3 in

A Differential Approach to Geometry: Geometric Trilogy III
The name nephroid refers to the shape of this kidney-shaped curve. • A
parametric representation is given by f(t) = R(3 sint − sin3t,3 cost − cos 3t). • The
length is 24R. • The area is 12πR2. • The evolute is another nephroid, twice
smaller.
The last exercise shows that the tangent to the nephroid, regarded as a chord of
the circumscribing circle, is divided in the ratio 3 : 1 at the point of contact. Thus if
UQ (Fig. 49) touches the evolute at P', P'Q = \UQ = \QP = $P'P. Calling the area ...

The embroidery of the nephroid is similar to that of the cardioid. The only
difference is that the chords of the base circle join points from A with points from A
