Ruby CMath cosh() Method with example

cosh() method is Math class which is used to returns the hyperbolic cosine of the given value.

Syntax: Math.cosh(z) Parameter: Here, z is the value whose hyperbolic cosine is to be calculated. Returns: This method returns the hyperbolic cosine value of the z.

Example 1:

Ruby

# 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"

Output:

cosh value of a : 1.0649157114377563

cosh value of b : 3.7621956910836314

Example 2:

Ruby

# 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"

Output:

cosh value of a : 1.0

cosh value of b : 1.0306599031548231
