False position method . "Double false position" is aimed at solving more difficult problems that can be written algebraically in the form: determine such that if it is known that Double false position is mathematically equivalent to linear interpolation. By using a pair of test inputs and the corresponding pair of outputs, the result of this algorithm given by, would be memorized and carried out by rote. Indeed, the rule as given by Robert Recorde in his "Ground of Artes" (c. 1542) is: <poem> For an affine linear function, double false position provides the exact solution, while for a nonlinear function it provides
Midfielder mark specific opposition attackers. Defensive midfielders may also move to the full-back or centre-back positions if those players move forward to join in an attack. Sergio Busquets described his attitude: "The coach knows that I am an obedient player who likes to help out and if I have to run to the wing to cover someone's position, great." A good defensive midfielder needs good positional awareness, anticipation of opponent's play, marking, tackling, interceptions, passing and great stamina and strength (for their tackling). A holding or deep-lying midfielder stays close to their team's defence, while other midfielders may move forward to
