Web1 Answer. The proof you have is wrong. The thing is that the equation is a little vague. It doesn't mean that the equation is true for all values of in the sense: There exists such that for all , the equation holds. For each , there exists some such that the equation holds. So, your mistake is in the equality because is not a constant. Numerical integration methods can generally be described as combining evaluations of the integrand to get an approximation to the integral. The integrand is evaluated at a finite set of points called integration points and a weighted sum of these values is used to approximate the integral. The integration points and weights depend on the specific method used and the ac…
