### Cochleoid

Polar equation:
$r = a \sin( \theta )/ \theta$

### Description

The name means the snail-form curve. It was discussed by J Peck in 1700. The form given here is due to a Belgium Joseph Neuberg. The name originated in 1884 with writers Benthan and Falkenburg.

The points of contact of parallel tangents to the cochleoid lie on a strophoid.
