False position method of (written in modern notation) the equation . This is solved by false position, using a technique that predates formally written equations. First, guess that to obtain, on the left, . This guess is a good choice since it produces an integer value. However, 4 is not the solution of the original equation, as it gives a value which is three times too small. To compensate, multiply (currently set to 4) by 3 and substitute again to get , verifying that the solution is . Modern versions of the technique employ systematic ways of choosing new test values and are
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
