Math.Sinh メソッド

2008-03-28

指定された角度のハイパーボリックサインを返します。

Public Shared Function Sinh( _
   ByVal value As Double _) As Double
[C#]
public static double Sinh(doublevalue);
[C++]
public: static double Sinh(doublevalue);
[JScript]
public static function Sinh(
   value : double) : double;

パラメータ

value
ラジアンで計測した角度。

戻り値

value のハイパーボリックサイン。value が NegativeInfinity 、 PositiveInfinity 、 NaN のいずれかに等しい場合、このメソッドは value に等しい Double を返します。

解説

角度 value は、ラジアンで示す必要があります。π/180 を乗算して、度をラジアンに変換します。

使用例

[Visual Basic, C#, C++] 次に示すのは、 Sinh を使用して、選択した値からハイパーボリック恒等式を求める例です。
