Mar 16, 2023 · The definite integral can be used to calculate net signed area, which is the area above the \(x\)-axis less the area below the \(x\)-axis. Net signed area can be positive, negative, or zero. The component parts of the definite integral are the integrand, the variable of integration, and the limits of integration. And so when, let's do the easier case. When x is greater than or equal to negative two then x plus two is going to be positive, or it's going to be greater than ...AboutTranscript. Definite integrals represent the exact area under a given curve, and Riemann sums are used to approximate those areas. However, if we take Riemann sums with infinite rectangles of infinitely small width (using limits), we get the exact area, i.e. the definite integral! Created by Sal Khan.Integration by parts tends to be more useful when you are trying to integrate an expression whose factors are different types of functions (e.g. sin (x)*e^x or x^2*cos (x)). U-substitution is often better when you have compositions of functions (e.g. cos (x)*e^ (sin (x)) or cos (x)/ (sin (x)^2+1)). Comment. Definite Integral. A definite integral is an integral that gives a fixed value for a curve within the two given limits.
