Description : Hypocycloid curves are considered to be the domains for complex mappings, i.e. f(z) =sin(z) (first row) and f ( z ) 1 / z z (second row). Mathematical ornaments (ODEMA) made of copper polished by silver (shown by second coloumn) The patterned have been published in poster presentation ICM 2014 and in International Journal of Statistics and MathematicsVol. 1(3), pp. 016023, August, 2014.

PART C ODEMA 3D DESIGNED Description : Some ornaments here are designed by generalizing hypocycloid equations into 3 dimentional based on spherical coordinates. Some are also defined by the triple equations created by each derivative. The equation for 3 dimensional 3D hypocycloid :
a x sin a b cos b cos 1 b a y sin a b sin b sin 1 b z cos ; r / sin
(s.1) (s.2) (s.3)
The other surfaces are obtained by generalizing equation of ball. Instead of power of 2 for each term for a ball equation, one uses the ppower, i.e
xp yp zp r p .
