Second Fundamental Theorem of Calculus

The Second Fundamental Theorem of Calculus is an important theorem in calculus that connects the concepts of integration and differentiation. It provides a method for computing definite integrals by evaluating the antiderivative of a function at two endpoints. The theorem is often used in physics, engineering, and other sciences to solve problems involving motion, velocity, and acceleration. The Second Fundamental Theorem of Calculus states that if f(x) is a continuous function on the interval [a, b] and F(x) is an antiderivative of f(x), then the definite integral of f(x) from a to b can be computed by evaluating F(b) - F(a). In other words, the integral of a function is equal to the difference between its antiderivative evaluated at the upper and lower limits of integration.

Mathematically, we can write the Second Fundamental Theorem of Calculus as:

?[a,b] f(x) dx = F(b) - F(a) where F(x) is an antiderivative of f(x), also known as the indefinite integral of f(x). This theorem shows the relationship between the integral of a function and its antiderivative. The Second Fundamental Theorem of Calculus can be proven by using the First Fundamental Theorem of Calculus and the Mean Value Theorem for Integrals. Let's consider a function f(x) that is continuous on [a, b], and let F(x) be an antiderivative of f(x). Then, we can write: ?[a,b] f(x) dx = lim n?? ?i=1n f(xi) ?x where xi is a point in the ith subinterval [xi-1, xi] and ?x = (b-a)/n is the width of each subinterval. By the Mean Value Theorem for Integrals, we can find a point ci in each subinterval such that: f(ci) = 1/?x ?[xi-1,xi] f(x) dx

Substituting this expression into the previous equation, we get:

?[a,b] f(x) dx = lim n?? ?i=1n f(ci) ?x = lim n?? ?i=1n F'(ci) ?x (by the First Fundamental Theorem of Calculus) = F(b) - F(a) (by the definition of the definite integral) Therefore, we have proven the Second Fundamental Theorem of Calculus. The Second Fundamental Theorem of Calculus provides a powerful tool for evaluating definite integrals. It allows us to compute the area under a curve by finding an antiderivative of the function and evaluating it at the upper and lower limits of integration. This method is often simpler and more efficient than using the definition of the definite integral directly. In summary, the Second Fundamental Theorem of Calculus is a fundamental result in calculus that connects the concepts of integration and differentiation. It provides a method for evaluating definite integrals by computing the difference between the antiderivative of a function evaluated at two endpoints. This theorem has important applications in physics, engineering, and other sciences where problems involving motion, velocity, and acceleration are common.
