Que. No. 30
The backward differences of y, a function of equally spaced values of x are denoted by the operator
O A) sigma
B) alpha
C) dell
D) Delta​

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

The backward differences of y, a function of equally spaced values of x are denoted by the operator

A) sigma

B) alpha

C) dell

D) Delta

EVALUATION

The Newton's backward formula for an interpolating point x being near the end of the table. Newton's backward formula is given by

$\displaystyle \sf{f(x) = y_n + u. \Delta y_{n-1} + \frac{u(u + 1)}{2}{\Delta}^{2} y_{n-2} + .... }$

Hence from above we can conclude that the backward differences of y, a function of equally spaced values of x are denoted by the operator Delta

FINAL ANSWER

Hence the correct option is D) Delta
