Suppose James and Kathy have a rematch, but this time the official stops the contest after only 3 sec. For a continuous function y = f(x) whose graph is plotted as a curve, each value of x has a corresponding area function A(x), representing the area beneath the curve between 0 and x.The area A(x) may not be easily computable, but it is assumed to be well-defined.. The Second Fundamental Theorem of Calculus is the formal, more general statement of the preceding fact: if f is a continuous function and c is any constant, then A(x) = x cf(t)dt is the unique antiderivative of f that satisfies A(c) = 0. \label{meanvaluetheorem} \], Since \(f(x)\) is continuous on \([a,b]\), by the extreme value theorem (see section on Maxima and Minima), it assumes minimum and maximum values\(m\) and \(M\), respectivelyon \([a,b]\). The second fundamental theorem of calculus states that, if f (x) is continuous on the closed interval [a, b] and F (x) is the antiderivative of f (x), then ab f (x) dx = F (b) F (a) The second fundamental theorem is also known as the evaluation theorem. Answer: As per the fundamental theorem of calculus part 2 states that it holds for a continuous function on an open interval and a any point in I. The Fundamental Theorem of Calculus deals with integrals of the form ax f (t) dt. To really master limits and their applications, you need to practice problem-solving by simplifying complicated functions and breaking them down into smaller ones.
