benice Posted February 4, 2011 Report Share Posted February 4, 2011 The surface in above image is a portion of the graph ofsome mathematical equation. Let's do some brainstorming:Can you guess what's inside the surface? Answers: A funny 3D image: A funny curve: The above graphics were created completely using math formulas and math softwares.

benice Posted February 6, 2011 Author Report Share Posted February 6, 2011 Hint: Consider the intersection of a horizontal plane with the surface. The intersection consists of a family of funny curves.(An example curve is shown below. It has nothing to do with the answer.) Cut off the upper surface above the horizontal plane to get a funny 3D image. (This curve is obtained from another surface.) Quote Link to comment Share on other sites More sharing options...
Turtle Posted February 7, 2011 Report Share Posted February 7, 2011 Hint: Consider the intersection of a horizontal plane with the surface. The intersection consists of a family of funny curves....Cut off the upper surface above the horizontal plane to get a funny 3D image.... mmmm....how, in the most practical sense, do i/we make that cut? since we don't know the equation, we'd need some drawing software, oui/no? should we be able to do it in our heads? anyway, is it bunny rabbits? words? flipping the bird? :shrug: a turtle?

modest Posted February 7, 2011 Report Share Posted February 7, 2011 I don't know. Here are some curves roughly in the shape of the surface: without the background: Are we supposed to be guessing the equation that generated it? That sounds about impossible. ~modest EDIT----> Still no idea, but here is another rendition: Quote Link to comment Share on other sites More sharing options...
Qfwfq Posted February 7, 2011 Report Share Posted February 7, 2011 We might as well be trying to guess which flavours you'll choose, next time at the icecream shop. anyway, is it bunny rabbits? words? flipping the bird? :shrug: a turtle? :lol:Maybe he left his avatar as a hint, notice how it incorporates vesica piscis. You never know, anything is possible... Quote Link to comment Share on other sites More sharing options...
benice Posted February 8, 2011 Author Report Share Posted February 8, 2011 anyway, is it bunny rabbits? words? flipping the bird? :shrug: a turtle? You got it!There are two living things.The left one looks like a bird (or bird man). Quote Link to comment Share on other sites More sharing options...

CraigD Posted February 9, 2011 Report Share Posted February 9, 2011 A belated welcome to hypograph, benice! :) The surface in above image is a portion of the graph ofsome mathematical equation.I'm more intrigued by the mention of the image being the graph (in 3 dimensions, it appears) of an equation than by trying to guess what might be inside its outer surface. Can you give us the equation :QuestionM Quote Link to comment Share on other sites More sharing options...
