F(x) = speed or cost?


 * $$|\nabla u(x)|F(x) = 1$$

where F(x) is the speed at x.
 * $$|\nabla u(x)|=F(x)$$

where F(x) is the cost at x.

I removed the link to mathworld, which had no content except the definition of the equation (http://mathworld.wolfram.com/EikonalEquation.html): Who put that link? Why does wikipedia math systematically links to mathworld when almost all pages have much less content than the wikipedia page itself? —Preceding unsigned comment added by 84.77.5.45 (talk) 13:52, 29 May 2009 (UTC)

this page really needs tidying up! —Preceding unsigned comment added by 130.88.194.194 (talk) 15:38, 26 April 2011 (UTC)
