Find a langrange interpolating polynomial for nodes x[sub:k2ifryg0]0[/sub:k2ifryg0]=0 , x[sub:k2ifryg0]1[/sub:k2ifryg0]=1 ,x[sub:k2ifryg0]2[/sub:k2ifryg0]=4
for f(x)=(x)^ (1/2). Then write its error term.
work:
-------------
i have found the lagrange polynomial to be
L(x)= (-x[sup:k2ifryg0]2[/sup:k2ifryg0] +7x )/ 6
Im not sure how to find the error term.
need help. thanks in advance.
