Sounds like the Taylor polynomial with remainder, to me.

I can't think of a formal approach to this problem, but the is nothing but the Lagrange polynomial interpolation for a set of n+1 data points, while the second is the Taylor's series approximation of about

Look up the definition of a nth order Taylor's polynomial approximation about a point x=xo and you will have both questions answered.

But it would be more useful if someone could throw light on the derivation of the Taylor series expansion.
