Näherungsonstruktion
[edit]- Die Methode ähnelt der des Dreizehnecks
Ergebnis
[edit]Bezogen auf den Einheitskreis r = 1 [LE]
[edit]- Konstruierte Seitenlänge des 25-Ecks in GeoGebra (Anzeige max. 15 Nachkommastellen)
- Seitenlänge des 25-Ecks
- Absoluter Fehler der konstruierten Seitenlänge
- Bis zu den max. angezeigten 15 Nachkommastellen ist der absolute Fehler
- Konstruierter Zentriwinkel des 25-Ecks in GeoGebra (Anzeige signifikante 13 Nachkommastellen, gerundet)
- Zentriwinkel des 25-Ecks
- Absoluter Fehler des konstruierten Zentriwinkels
- Bis zu den gerundet angezeigten signifikanten 13 Nachkommastellen ist der absoluter Fehler
Beispiel um den Fehler zu verdeutlichen
[edit]Bei einem Umkreisradius r = 1 Mrd. km (das Licht bräuchte für diese Strecke ca. 55 min), wäre der absolute Fehler der konstruierten Seitenlänge < 1 mm.
Approximate construction
[edit]- The method is similar to that of the Tridecagon
Result
[edit]Based on the unit circle r = 1 [unit of length]
[edit]- Constructed side lenght of the icosipentagon in GeoGebra (Display max 15 decimal places)
- Side lenght of the icosipentagon
- Absolute error of the constructed side length
- Up to the max. displayed 15 decimal places is the absolute error
- Constructed central angle of the icosipentagon in GeoGebra (display significant 13 decimal places, rounded)
- Central angle of the icosipentagon
- Absolute error of the constructed central angle
- Up to the rounded significant 13 decimal places is the absolute error
Example to illustrate the error
[edit]At a circumscribed circle radius r = 1 billion km (the light needed for this distance about 55 minutes), the absolute error of the 1st side would be < 1 mm.
