False position method As a result, unlike the bisection method, the width of the bracket does not tend to zero (unless the zero is at an inflection point around which ). As a consequence, the linear approximation to , which is used to pick the false position, does not improve as rapidly as possible. One example of this phenomenon is the function on the initial bracket [−1,1]. The left end, −1, is never replaced (it does not change at first and after the first three iterations, is negative on the interval) and thus the width of the bracket never falls below 1. Hence,
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
