Gibt den Hyperbelsinus des angegebenen Winkels zurück.

public:
 static double Sinh(double value);

public static double Sinh (double value);

static member Sinh : double -> double

Public Shared Function Sinh (value As Double) As Double

Parameter

value: Double

Ein im Bogenmaß angegebener Winkel.

Gibt zurück

Double

Der Hyperbelsinus von value. Wenn value gleich NegativeInfinity, PositiveInfinity oder NaN ist, gibt diese Methode einen Double mit dem Wert value zurück.

Beispiele

Im folgenden Beispiel werden Sinh bestimmte hyperbolische Identitäten für ausgewählte Werte ausgewertet.

Hinweise

Der Winkel muss valuebogenmaßend sein. Multiplizieren Sie mit Math.PI/180, um Grad in Bogenmaße zu konvertieren.

Diese Methode ruft die zugrunde liegende C-Runtime auf, und das genaue Ergebnis oder der gültige Eingabebereich kann sich zwischen verschiedenen Betriebssystemen oder Architekturen unterscheiden.
