Newton interpolary difference formula

  1. Feb 25, 2017 #1
    1. The problem statement, all variables and given/known data
    I dont understand the meaning of the formula.... For the circled part in the first photo , what is the meaning of f(x1 ,x2 ) ? and also f(x0 , x1 ) ?
    2. Relevant equations


    3. The attempt at a solution
    I used the highlighted formula to find the second divided difference . But , Here's what i gt :

    f(x1 ,x2 ) - f(x0 , x1 ) / ( x2 -x0 )
    =
    (0.510*0.381)-(0.521*0.510) / (2.6-2.1) , I ended up getting -0.143
