Mengembalikan kosinus hiperbolik dari sudut yang ditentukan.

public:
 static double Cosh(double value);

public static double Cosh (double value);

static member Cosh : double -> double

Public Shared Function Cosh (value As Double) As Double

Parameter

value: Double

Sudut, diukur dalam radian.

Mengembalikan

Double

Kosinus hiperbolik .value Jika value sama dengan NegativeInfinity atau PositiveInfinity, PositiveInfinity dikembalikan. Jika value sama dengan NaN, NaN dikembalikan.

Contoh

Contoh berikut menggunakan Cosh untuk mengevaluasi identitas hiperbolik tertentu untuk nilai yang dipilih.
