Noun
integrand (plural integrands)
(calculus) The function that is to be integrated
A refinement of this method, known as importance sampling in statistics, involves sampling the points randomly, but more frequently where the integrand is large. Source: Internet
A "proper" Riemann integral assumes the integrand is defined and finite on a closed and bounded interval, bracketed by the limits of integration. Source: Internet
Simpson's rule approximates the integrand by a piecewise quadratic function. Source: Internet
Since the integrand is a non-negative real-valued function, there is no difference between having a finite Lebesgue integral and having a finite improper integral (as there is say for the function sin(x)/x when integrated over the entire real line). Source: Internet
The function f(x) to be integrated is called the integrand. Source: Internet
The result is that when you integrate the real part of the integrand you get a relatively large number (in this case 0.5). Source: Internet
