Riemann Sums app for iPhone and iPad

If you have a function you want to integrate, but you’d rather let a computer make a really close approximation then actually doing it by hand, then this app is for you.

Riemann Sums uses Riemann’s summation techniques to compute integrals. After entering your function and range, press “calculate”, and you’ll be prompted to choose from 4 different summation methods. These include

•Left (Bottom)
•Right (Top)
•Middle (Mid-Point)
•Trapezoid


Our built in library supports the use of most common functions including logarithmic, trigonometric, inverse trigonometric and hyperbolic functions. Popular constants are built in as well. These include: Pi, Phi, Tau, sqrt2, e, log2e, log10e, ln2 and ln10.

After you’ve calculated an integral, your results are saved in the history section so they can be viewed again at any time. Results can also be shared via iCloud, SMS, Email, Facebook, Twitter, Weibo.
