参数
- value
- Complex
一个复数。A complex number.
返回
value 的双曲余弦值。The hyperbolic cosine of value.
注解
Cosh复数的方法与实数的方法相对应 Math.Cosh 。The Cosh method for complex numbers corresponds to the Math.Cosh method for real numbers.
Cosh方法使用以下公式来计算复数 a + bi 的双曲余弦值:The Cosh method uses the following formula to calculate the hyperbolic cosine of the complex number a + bi:
(Cosh () () () Cos Sinh () ) Sin(Cosh(a) * Cos(b), Sinh(a) * Sin(b))
