Question

Advantages and disadvantages of newton forwanrd interpolation

Answer 1

Forward interpolation formula is used to interpolate the values of y nearer to the beginning value of the given table.Also this formula is applicable if in case where h(difference in intravel) is constant .

Now coming to backward difference formula.

This formula is used to interpolate the values of y nearer to the end of the table (or) tabular values .

These are the places,where we need to apply those formulas .

These formulas are used when the intravels for computing a value of a function are equidistant
