The inverse of the reciprocal of the absolute value of 1 / 3-1 is[

The absolute value of 1 / 3-1 = - 2 / 3 is 2 / 3, the reciprocal of is 3 / 2, and the inverse of is - 3 / 2

Given the function f (x) = 3x-2 / 2x-1, find the value of F (1 / 2010) + F (2 / 2010) +... + F (2009 / 2010)

F (x) = (3x-2) / (2x-1); f (1-x) = (3x-1) / (2x-1); f (x) + F (1-x) = 3 (2x-1) / (2x-1) = 3; therefore, f (1 / 2010) + F (2009 / 2010) = 3F (2 / 2010) + F (2008 / 2010) = 3f (3 / 2010) + F (2007 / 2010) = 3 Original formula = 1005 * 3 = 3015
