xcthulhu Posted July 16, 2011 Share Posted July 16, 2011 There was a post a while back on "1/0", and I was disappointed to see a post of mine deleted. So I'll be brief and repeat my previous remark. While 1/0 is generally undefined for fields, it is defined on the Riemann Sphere for the so-called extended complex numbers. On this complex manifold, 1/0 = [tex]\infty[/tex], the "point at infinity". Wolfram|Alpha and Mathematica implement this sort of complex arithmetic, albeit a bit inconsistently. Here's what Wolfram|Alpha thinks 1/0 is: http://www.wolframalpha.com/input/?i=1%2F0 Link to comment Share on other sites More sharing options...

xcthulhu Posted July 17, 2011 Author Share Posted July 17, 2011 No question really, just registering a complaint. I'll get off my soap-box now I suppose. Link to comment Share on other sites More sharing options...
swansont Posted July 17, 2011 Share Posted July 17, 2011 The latex tags use math [math]\infty[/math] gives you [math]\infty[/math] I don't see where any posts have been deleted. Link to comment Share on other sites More sharing options...
