I feel kinda retarded asking this since I've actually taken math in uni several years ago, buuut... What I have is this: x4 - 5x2 + y4 - 5y2 + z4 - 5z2 + 11.8 = 0 I suppose the easiest way would be to convert this to polar form, which would give me:

  x4           x2
----- - ------------------ + ... = 1
-11.8   (sqrt(-11.8) / 5)2

Now, on my part I see several problems with this, the most important of which are: 1) I'm taking a square root of a negative number 2) I don't know how to go about extracting x, y and z from that I've mentioned before that I'm mathematically challenged, so I hope someone's willing to hand-walk me through this :) Cheers
