False position method double false position formula on that line segment. More precisely, suppose that in the -th iteration the bracketing interval is . Construct the line through the points and , as illustrated. This line is a secant or chord of the graph of the function . In point-slope form, its equation is given by Now choose to be the -intercept of this line, that is, the value of for which , and substitute these values to obtain Solving this equation for "c" gives: This last symmetrical form has a computational advantage: As a solution is approached, and will be very close
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.
