About the denomination of an elliptic arc

  1. Jan 8, 2012 #1
    Hi all,

    Does anyone know the specific names of the high-curvature arc and the low-curvature arc on an ellipse? Or, do they have special names after all?
    Anyone help me figure this out, thank you very much!!!
    Regards.

    The middle of the tightly curved bits are called vertices, but the curved bit itself has no special name.
    You'd refer to it as a vertex arc.

    I was wondering if maybe the arcs could be episcopalian and dominican ... but figured that wasn't what you meant :) I think the word you were looking for is "nomenclature".

    No worries - have fun.
