Question 10 :

equation (9) is:

10. Prove that the coefficient of a" in the polynomial p of Equation (9) is (di - r;) -1 1=0 j=0The alternative method will express p in the form pa) = meats) + 19151 (as) + . . - + mes) = Zykem) (9) 16:0 Here 90,61, . . . , En are polynomials that depend on the nodes mg, :31, . . . ,mn but not on the ordinates y0,y1, . . . , yn. Since the ordinates could be all 0 except for 1 occupying
