Riemann Sum for a Definite Integral
- Dick Lane
- Definite Integral
The region between x-axis and graph of function f on interval [a,b] has (net) area which can be approximated by Riemann Sums computing total area for a collection of adjacent rectangles with one side on axis and opposite side with a corner on the graph.
- Function f can be revised by typing a new expression in upper-right box.
- Ends of interval [a,b] can be changed by dragging points on x-axis or entering new values in labeled boxes. Note that the corresponding part of the graph is thickened.
- Choose number of rectangles with slider for n.
- Use the checkboxes to choose what to display.
