What is the Riemann formula? The Riemann sum formula is: A = sum f(x)*Delta x, where A is the area under the curve, f(x) is the height of each rectangle (or the average of the two heights for a trapezoid), and Delta x is the width of each rectangle or trapezoid. In essence...
The type of Riemann Sum at the top of the graph, The number of rectangles (or trapezoids) by dragging the slider, The start and end points of the graph, by dragging the sliders. Simple Example Update (May 2014): This applet has been updated, improved and moved, and you can now find...
For other unsolved math problems which also hold out the promise of $1 million, see:Unsolved Math Problemsfrom Wolfram's MathWorld. 4. Math movie: Is math discovered or invented? I quite like the idea that mathematics is simply "out there" and our job is to discover it. But others have...
