 Author Comment/Response Bill 08/27/08 3:09pm Hi: Example: A.) Find the smallest and greatest individual xyz coordinate point values, for the sets of points generated by: data = Table[{3*Cos[t], 3*Sin[t], 2*t}, {t, 0, 30}] // N (* Grid[data, Alignment -> Decimal] <-This line is just for displaying the output in an easy to read form.*) B.) Identify the coordinate sets that contain the lowest and greatest xyz values: (*I arrived at the following by making visual comparisons of "data".*) The least and greatest coordinate values for x are: -2.99988 and 3. The coordinate sets that contain the least and greatest x coordinates respectively are: {-2.99988, -0.0265539, 44.} and {3, 0, 0.}. The least and greatest coordinate values for y are: -2.99997 and 2.97182. The coordinate sets that contain the least and greatest y coordinates respectively are: {0.0132771, -2.99997, 22.} and {0.410212, 2.97182, 28.}. The least and greatest coordinate values for z are: 0 and 60. The coordinate sets that contain the least and greatest z coordinates respectively are: {3, 0, 0} and {0.462754, -2.96409, 60.}. Question: How do I code Mathematica to find and return the smallest and greatest coordinate point values for the x,y and z coordinates respectively, and the coordinate sets that contain them? Thanks, Bill PS. I'm using Mathematica 6.0.1 on a pc with Windows XP. URL: ,
