If h ≠ 0, then the difference quotient can be simplified into the form A + Bh + Ch^2. That is:
(f(x+h) - f(x)) / h = A + Bh + Ch^2
where the coefficients A, B, and C can be functions of x or just constant terms. Find these coefficients:
A = , B =
(Note: It's possible for one or more of these coefficients to be 0.)
If h ≠ 0, then the difference quotient can be simplified into the form ABh + Ch. That is: f(x+h) f()
where the coefficients A, B, and C can be functions of or just constant terms. Find these coefficients: B =
(Note: It's possible for one or more of these coefficients to be 0.)
