4.Kies de eenheid waarvan u wilt converteren.

5.Druk tweemaal op [ ].

zSelecteer " DMS " om de vooraf ingevoerde hoekwaarde naar de DMS-notatie te converteren. Als het resultaat van deze conversie bijvoorbeeld 1°30′0″ zou zijn, dan is de waarde van de hoek: 1 graad, 30 minuten en 0 seconden. Zie Voorbeeld 33.

zOm een DMS-notatie naar een decimale notatie te converteren, selecteert u ° (graden), ′ (minuten), ″ (seconden). Zie Voorbeeld 34.

„Trigonometrische / inverse trigonometrische functies

De rekenmachine is voorzien van de standaard trigonometrische functies en inverse trigonometrische functies - sin, cos, tan, sin –1, cos –1en tan –1. Zie Voorbeeld 35~37.

(Opmerking) : Wanneer u deze toetsen gebruikt, moet u ervoor zorgen dat de rekenmachine ingesteld staat op de gewenste hoekeenheid.

„Hyperbolische en inverse hyperbolische functies

De rekenmachine gebruikt [ 2nd ] [ HYP ] om de hyperbolische en inverse hyperbolische functies, – sinh, cosh, tanh, sinh –1, cosh –1en tanh –1te berekenen. Zie Voorbeeld 38~39.

(Opmerking) : Wanneer u deze toetsen gebruikt, moet u ervoor zorgen dat de rekenmachine ingesteld staat op de gewenste hoekeenheid.

„Coördinaattransformatie

Druk op [ 2nd ] [ RP ] om een menu weer te geven voor de conversie van rechthoekige coördinaten naar polaire coördinaten of omgekeerd. Zie Voorbeeld 40~41.

Rechthoekige coördinaten

Polaire coördinaten

x + y i = r (cosθ+ i sinθ)

(Opmerking) : Wanneer u deze toetsen gebruikt, moet u ervoor zorgen dat de rekenmachine ingesteld staat op de gewenste hoekeenheid.
