Ruby CMath tan() Method with example

  • Last Updated : 07 Jan, 2020

tan() method is Math class which is used to returns the tangent of the given value.

Syntax: Math.tan(z)

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

Returns: This method returns the tangent value of the z.

Example 1:






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

Output:

tan value of a : 0.374577262964287

tan value of b : -2.185039863261519

Example 2:




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

Output:

tan value of a : 0.0

tan value of b : -0.2521487591957248
