Hi, 14th II is comming so I thought to draw some hearts, i know the formula but i don't know how to draw it using mathematica, could anyone help me with it ? Here's formula: (2x^2 + y^2 + z^2 -1)^3 = a*x^2*z^3 -y^2*z^3, where a is a real-noumber value. Chris -- Serwis Usenet w portalu Gazeta.pl -> http://www.gazeta.pl/usenet/
