A curve on a surface of revolution that cuts all the meridians at a constant angle . If is an acute or obtuse angle, then a loxodrome performs infinitely many windings about the pole, getting closer and closer to it.

Figure: l060970a

For surfaces of revolution whose first fundamental form can be written as

the equation of a loxodrome is

For a sphere with first fundamental form

the equation of a loxodrome is
