    [SOLVED] Higher Order Interpolation

    I've been going over this problem again and again and I can't seem to figure out what interpolation method to use.

    If f \in C^2[a,b] and a = x_0 < x_1 < \cdots < x_n = b, and the following values are given:
    f(x_0)\quad f(x_1)\: \cdots \: f(x_n)
    f'(x_0)\quad f'(x_1)\: \cdots \: f'(x_n)
    f''(x_0)\quad f''(x_1)\: \cdots \: f''(x_n)

    Give a formula for the (unique) polynomial K_{3n+2}(x) of degree \leq 3n+2 where K_{3n+2}(x_j) = f(x_j), K'_{3n+2}(x_j) = f'(x_j) and K''_{3n+2}(x_j) = f''(x_j) for j=0,\ldots,n

    I'd really appreciate any help you could offer. Thanks a lot!

    Well, the right method to use was Hermite interpolation, but my textbook never specified that it could go beyond K(x_i) = f(x_i)\text{ and } K'(x_i) = f'(x_i)...
    I've submitted a new thread asking about that.
