Approximate Integration. To approximate the definite integral we split the region up into many thin slices. For each slice we may approximate its area using rectangles, in which case we could either ...

Drag the slider labeled "position" to change the point used for the height of the rectangle. The sum of the areas of all the thin rectangles is the Riemann Sum displayed. If you wish to change the ...

A Java applet, which makes use of Green's functions calculations inside a rectangular cavity, is presented. The emission level of integrated circuits inside the cavity is examined. The circuits are ...
