WebNov 10, 2024 · Definition: Critical Points Let c be an interior point in the domain of f. We say that c is a critical point of f if f ′ (c) = 0 or f ′ (c) is undefined. As mentioned earlier, if f has a local extremum at a point x = c, then c must be a critical point of f. This fact is known as Fermat’s theorem.

WebAuthor(s): Ausilio, Ernesto; Durante, Maria Giovanna; Zimmaro, Paolo Abstract: The performance of a large number of critical infrastructure systems needs to be periodically re-evaluated. This is especially so when such systems are located in seismic areas and are subjected to ageing effects. Seismic re-evaluations are typically performed using … WebCritical Point of a Function Definition. Based upon the above discussion, a critical point of a function is mathematically defined as follows. A point (c, f(c)) is a critical point of a continuous function y = f(x) if and only if. c is in the domain of f(x). Either f '(c) = 0 or f'(c) is NOT defined.
