and oblique prisms with bases of any shape, such as triangles, quadrilaterals, or other polygons... | {"url":"https://www.brightstorm.com/math/geometry/volume/volume-of-prisms/","timestamp":"2014-04-19T10:10:45Z","content_type":null,"content_length":"57150","record_id":"<urn:uuid:215a2e91-05ed-4967-bcaa-94958e3fa9dd>","cc-path":"CC-MAIN-2014-15/segments/1398223206118.10/warc/CC-MAIN-20140423032006-00071-ip-10-147-4-33.... |

Windows of periodicity
It is a commonly observed feature of chaotic dynamical systems [1] that, as a system parameter is varied, a stable period-n orbit appears (by a tangent bifurcation) which then undergoes a
period-doubling cascade to chaos and finally terminates via a crisis.

Computing the Mahalanobis distance with the Perl Data Language
Many machine learning and data analysis tasks involve calculating distances between items. The Mahalanobis distance is a very popular distance because it is scale invariant.

Manipulating Lists by Their Indices
You can always reset one or more pieces of a list by doing an assignment like .
It is sometimes useful to think of a nested list as being laid out in space, with each element at a coordinate position given by its indices. There is then a direct geometrical interpretation for .
