Rules to find maxima and minima
WebbThe method of maxima and minima is used by Fermat in determining tangents, observing that the difference between a curve and its tangent has in the tangent point a minimum (or maximum) (see below), but this also finds other applications. Fermat writes: WebbMore precisely, ( x, f ( x)) is a local maximum if there is an interval ( a, b) with a < x < b and f ( x) ≥ f ( z) for every z in both ( a, b) and the domain of f. Similarly, ( x, y) is a local minimum point if it has locally the smallest y coordinate.
