Näherungsonstruktion

Ergebnis

Bezogen auf den Einheitskreis r = 1 [LE]

  • Konstruierte Seite des Neunzehnecks in GeoGebra
  • Seite des Neunzehnecks
  • Absoluter Fehler der konstruierten Seitenlänge
  • Konstruierter Zentriwinkel des Neunzehnecks in GeoGebra
  • Zentriwinkel des Neunzehnecks
  • Absoluter Fehler des konstruierten Zentriwinkels

Beispiel um den Fehler zu verdeutlichen

Bei einem Radius r = 1 Mrd. km (das Licht bräuchte für diese Strecke ca. 56 min) wäre der absolute Fehler der konstruierten Seitenlänge ca. 0,21 mm.

Approximate construction

Score

Based on the unit circle r = 1 [unit of length]

  • Constructed side length of the enneadecagon in GeoGebra
  • Side length of the enneadecagon
  • Absolute error of the constructed side length
  • Constructed central angle of the enneadecagon in GeoGebra
  • Central angle of the enneadecagon
  • Absolute error of the constructed central angle

Example to illustrate the error

At a radius r = 1 billion km (the light would need about 56 min for this distance) the absolute error of the side length constructed would be approx. 0.21 mm.
