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 as wingers behind a lone striker. In a three-man midfield, specialist wingers are sometimes deployed down the flanks alongside the central midfielder or playmaker. Even more demanding is the role of wing-back, where the wide player is expected to provide both defence and attack. As the role of winger can be classed as a forward or a midfielder, so this role blurs the divide between defender and midfielder. A winger is an attacking midfielder who is stationed in a wide position near the touchlines. Wingers such as Stanley Matthews or Jimmy Johnstone used to be classified as forwards in traditional
