NettetWhat Is the Definition of Definite Integral? The definite integral is used to find the area of the curve, and it is represented as \(\int^b_af(x).dx\), where a is the lower limit and b is the upper limit., for a function f(x), defined with reference to the x-axis. The definite integrals is the antiderivative of the function f(x) to obtain the function F(x), and the … Nettet20. des. 2024 · If we change variables in the integrand, the limits of integration change as well. Substitution with Definite Integrals Let u = g(x) and let g ′ be continuous over an interval [a, b], and let f be continuous over the range of u = g(x). Then, ∫b af(g(x))g′ (x)dx = ∫g ( b) g ( a) f(u)du.
