upper riemann sum definition In mathematics a Riemann sum is a certain kind of approximation of an integral by a finite sum It is named after nineteenth century German mathematician Bernhard Riemann One very common application is in numerical integration i e approximating the area of functions or lines on a graph where it is also known as the rectangle rule It can also be applied for approximating the lengt
One perhaps the way of defining the Riemann upper sum is as follows U n i 1f x i xi where xi xi xi 1 x i xi 1 xi and f x i sup f xi 1 xi that is Author Dr Adrian Jannetta Topic Area Upper and Lower Sum or Riemann Sum This applet shows how upper and lower Riemann sums can approximate an integral Further they show that as the number of strips increases the

A Riemann sum is an approximation of a region s area obtained by adding up the areas of multiple simplified slices of the region It is applied in calculus to formalize the method of exhaustion used to determine the area of a region A Riemann sum is defined for f x as n i 1f x i x Recall that with the left and right endpoint approximations the estimates seem to get better and better as n get larger and larger The same thing happens with Riemann sums
Riemann Sums The definition of a Riemann sum is the same as that of the area formula we used in section 4 2 with the following generalizations The bases of the rectangles no longer De nition Upper and Lower Riemann Sums Assume that f x is bounded on a b Let P be a partition on a b Let Mi lub ff x x 2 ti 1 ti g and let mi glb ff x x 2 ti 1 ti g Then mi
