False position method double false position became a root-finding algorithm used in iterative numerical approximation techniques. Many equations, including most of the more complicated ones, can be solved only by iterative numerical approximation. This consists of trial and error, in which various values of the unknown quantity are tried. That trial-and-error may be guided by calculating, at each step of the procedure, a new estimate for the solution. There are many ways to arrive at a calculated-estimate and "regula falsi" provides one of these. Given an equation, move all of its terms to one side so that it has the form, , where
Midfielder a wide midfielder, a shuttler, somebody who might be expected to cross a ball but was also meant to put in a defensive shift." A notable example of a right midfielder is David Beckham. The historic position of wing half (half-back) was given to midfielders who played near the side of the pitch. It became obsolete as wide players with defensive duties have tended to become more a part of the defence as full-backs. Defensive midfielders are midfield players who focus on protecting their team's goal. These players may defend a zone in front of their team's defence, or man
