Fish Curve

A fish curve is an ellipse negative pedal curve that is shaped like a fish. In a fish curve, the pedal point is at the focus for the special case of the eccentricity . Fish curves can correspond to ellipses with parametric equations. In mathematics, parametric equations are a method of expressing a set of related quantities as explicit functions of a number of independent variables, known as “parameters.” For example, rather than a function relating variables x and y in a Cartesian coordinate system such as, a parametric equation describes a position along the curve at time t by and . Then x and y are related to each other through their dependence on the parameter t. The fish curve is a kinematical example, using a time parameter to determine the position, velocity, and other information about a body in motion.

Famous quotes containing the words fish and/or curve:

    Little fish swam by his nose
    and he noted them and touched their slime.
    Plankton came and he held them in his palm
    like God’s littlest light bulbs.
    Anne Sexton (1928–1974)

    And out again I curve and flow
    To join the brimming river,
    For men may come and men may go,
    But I go on forever.
    Alfred Tennyson (1809–1892)
