    How to find the Newton Polynomial Approximation?

    I need to find the Newton Polynomial Approximation for f(x) = 1/(sqrt(1-x)) on the interval [-1.5, 0.95] and to investigate which polynomial order is more sufficient for an accurate representation of the above function.

    I honestly have no idea how to go about this and I tried to understand it with Wikipedia Newton polynomial - Wikipedia, the free encyclopedia but it's beyond me.

    As much as I would like the answer, I would also like to understand this so any help is greatly appreciated.

    PS. Wasn't sure which category this went under so I've put it here.

    Re: How to find the Newton Polynomial Approximation?

    With an interpolation problem, it is usual to be given some number of points the problem then being to find a polynomial passing through those points. Do you have such a set or are we free to choose whatever and however many we want ?
