5), we get an = f (x) = f (a + nh) + (x – a – nh) ∇ 2 f ( a + nh) ∇f ( a + nh) + (x – a – nh) (x – a – (n – 1)h) 2 ! h2 h n + ...... + (x – a – nh) (x – a – (n – 1)h) ...... (x – a – h) ∇ f ( a + nh) n ! 6), we get f (a + nh + hu) = f (a + nh) + u∇f (a + nh) + + ..... + u(u + 1) 2 ∇ f (a + nh) 2! u(u + 1) (u + 2) ...... (u + n − 1) n ∇ f (a + nh). n! 4. , xn not necessarily equally spaced. Since there are (n + 1) values of f (x) so (n + 1)th difference is zero. Thus f (x) is supposed to be polynomial in x of degree n.

On solving we get X1 and X2. 2. , a + nh respectively where h is the difference of the arguments. Let f (x) be a polynomial in x of degree n. So f (x) can be written as f (x) = a0 + a1(x – a) + a2 (x – a) (x – a – h) + a3 (x – a) (x – a – h) (x – a – 2h) + ...... + an (x – a) (x – a – h) ..... h 2h2 a2 = f (a + 2h) – 2ha1 – a0 a2 = = f ( a + 2h) − 2( f ( a + h) − f ( a)) − f ( a) 2 ! h2 f ( a + 2h) − 2 f ( a + h) + f ( a) ∆2 f ( a) = 2 ! h2 2 ! h2 23 INTERPOLATION Proceeding in the same way, we get a3 = ∆3 f ( a) ......
