Question

For Newton's Forward Interpolation Formula, u should be always *

1.positive

2.negative

3.not defined

4.none of these

​

Answer 1

Answer:

2.negative

I think you are asking here about the lens convention.

You can just imagine an x-y graph. On the right, it's +ve and on the left, it's - ve.

Answer 2

Answer:

This formula is particularly useful for interpolating the values of f(x) near the beginning of the set of values given. h is called the interval of difference and u = ( x – a ) / h, Here a is first term. Below is the implementation of newton forward interpolation method
