Imaginary zeros of f(z)= z^(1/z) (real valued solutions f(z)>e^(1/e))

A cardioid is a shape that is very similar to this, and I thought I'd try and approximate it. It turns out its not a cardioid, but its very close, and can be approximated with the parametric equations:

\( x(t) = a \cos(t) (1+\cos(ct)) \)
\( y(t) = a \sin(t) (1+\cos(ct)) \)

where a = 1.36 and c = 1.17

Andrew Robbins

Perhaps this can be also used? It has similar shape and parametrization, but different place for coefficients, and is more general then cardioid.

Limacon?
