WebRiemanns Integral¶. The simplest method for approximating integrals is by summing the area of rectangles that are defined for each subinterval. The width of the rectangle is $x_{i+1} - x_i = h$, and the height is defined by a function value $f(x)$ for some $x$ in the subinterval. An obvious choice for the height is the function value at the left endpoint, … Web(1) If 𝒈(𝒙) = 𝒙 the Riemann–Stieltjes integral reduces to the Riemann integral. (2) The function 𝒈(𝒙) need not be continuous. (3) The following theorem is of importance in the study of stochastic integral.
