  Emergent Ellipsoids
    DF   =   Vector   =   x2
    AB   =   Major Diameter   =   2x2
    DE   =   Minor Diameter   =   SqRt(x42x3+x2)
    FG   =   wave   =   2(x2x)
    FH   =   hypotenuse   =   2x22x+
    GH   =   radius   =   2x
    HK   =   Vector radius   =   x2
Extend the Minor Diameter, Line DE, as required.
Lines CI and CJ equal Lines AF and BG.
Draw Lines IK and JK such that they equal the Vector.
