How to Convert a Riemann Sum to a Definite Integral - YouTube

Web28 Mar 2015 · The Riemann sum is an approximation of the integral and per se not "exact". You approximate the area of a (small) stripe of width dx, say between x and x+dx, and f (x) with the area of an rectangle of the same width and the height of f (x) as it's left upper corner. If the function changes it's value when you go from x to x+dx then the area of ... WebThe Integral Calculator lets you calculate integrals and antiderivatives of functions online — for free!
