    Hi,

    I was wondering if anyone could check this explanation of Differentiation from first principles for me. It is different from what my teacher taught me, and makes more sense to me than his explanation did.

    Any help would be great.

    Thanks.

    The explanation is excellent--this is exactly how I learned about the derivative and how its definition is derived. This is also how Newton would have went about interpreting the derivative.
