Ruby CMath tan() Method with example

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
