Ruby CMath cosh() 方法与示例

cosh() 方法是 Math 类，用于返回给定值的双曲余弦值。

Syntax: Math.cosh(z)

Parameter: Here, z is the value whose hyberbolic cosine is to be calculated.

Returns: This method returns the hyberbolic cosine value of the z.

示例 1：

# Ruby code for cosh() method
require 'cmath'
  
# Initializing value  
a = 0.3584
b = 2
  
# Printing result   
puts "cosh value of a : #{CMath.cosh(a)}\n\n"  
puts "cosh value of b : #{CMath.cosh(b)}\n\n"

输出：

cosh value of a : 1.0649157114377563

cosh value of b : 3.7621956910836314

示例 2：

# Ruby code for cosh() method
require 'cmath'
  
# Initializing values  
a = 0
b = -0.247
  
# Printing result   
puts "cosh value of a : #{CMath.cosh(a)}\n\n"  
puts "cosh value of b : #{CMath.cosh(b)}\n\n"

输出：

cosh value of a : 1.0

cosh value of b : 1.0306599031548231
