This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Visualized estimate for the Cauchy condensation test.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
Summary
DescriptionVisualized estimate for the Cauchy condensation test.png
English: Visual aid for a proof of the Cauchy condensation test.
The leftmost image represents a (truncation of a) series of non-negative, non-increasing terms. The center image represents the corresponding condensed series, with the original overlayed to show it is greater. The rightmost image is the original series with each term duplicated once (so that the whole series is doubled), with both the left ones overlayed to show it greater than both.
