Riemann Sum

Riemann Sum is a lightweight Windows application built specifically for helping you calculate the Riemann sum for various functions and view the relationship between the Riemann sum and integral of a function.
Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.
You can copy it on any USB flash drive or other devices, and take it with you whenever you need to perform math calculations on the fly, without having to go through installation steps.
Riemann Sum sports a clean and intuitive layout that offers only a few configuration settings to tinker with.
The tool gives you the possibility to adjust the width of the slices pretty easily, thanks to its built-in slider, select the type of function that you want to render (horizontal, increasing, decreasing, semicircle, or polynomial function), as well as view the calculated and actual areas.
What’s more, the relationship between the width of slices and estimation errors is displayed with the use of a graph. It would have been useful to see support for an exporting option.
During our testing we have noticed that Riemann Sum carries out a task very quickly, and no errors showed up throughout the entire process. It leaves a minimal footprint on system resources, so the overall performance of the computer is not hampered.
All things considered, Riemann Sum proves be a reliable application that packs a handy set of feature for helping you calculate the Riemann sum. Thanks to its intuitive layout, it is suitable for rookies and professionals alike.
