Definition:Latitude Circle of Surface of Revolution

Definition

Let $S_C$ be a surface of revolution.

Let its smooth local parametrization be of the form:

$\map X {t, \theta} = \tuple {\map y t \cos \theta, \map y t \sin \theta, \map x t}$

Then the $\theta$-coordinate curves $\theta \mapsto \map X {t_0, \theta}$ are called the latitude circles.
