Taylor's Theorem

[Maverick848]

At the wikipedia site <http://en.wikipedia.org/wiki/Taylor's_theorem> the mean value was used to do a step in the proof of Taylor's Theorem. I do not understand the line that follows:

"The remainder term in the Lagrange form can be derived by the mean value theorem in the following way:"









Also, how could I copy and paste that line to this site?

I tried looking at the site but they claim they can't find it.

Its near the bottom of the section entitled:

"Proof: Taylor's theorem in one variable"
