Ruby – Find Tangent – tan() Method – Examples & Explanation

In Ruby, tan() method can be used to find the tangent of the any given complex number in Ruby language where this number is given in radians. tan() method exists in CMath library of Ruby programming language.

tan() method in Ruby

tan() method exists in Standard tan() Library of Ruby. The purpose of this method is to provide perfect tangent for any given complex number where this number is given in radians.

Syntax of the tan() method in Ruby

Syntax of tan() method is cmath.tan(x)

Parameters of tan() method in Ruby

Parameter Description
xAny valid complex number. This parameter is required.

Note: if the x parameter is not a complex number, tan() method will return an error.

Return Value of tan()

tan() method will return the tangent of any given complex number where this number is given in radians.

Ruby tan() Example 1

# import CMath library
require 'cmath'
x = CMath.tan(5 + 5i)
puts x
# -4.9400804073229665e-05+1.0000761892591823i

Ruby tan() Example 2

# import CMath library
require 'cmath'
x = CMath.tan(-5 + 5i)
puts x
# 4.9400804073229665e-05+1.0000761892591823i

Ruby tan() Example 3

# import CMath library
require 'cmath'
x = CMath.tan(a5 - b5i)
puts x
# Error

Ruby tan() Example 4

# import CMath library
require 'cmath'
x = CMath.tan(-5 - 5i)
puts x
# 4.9400804073229665e-05-1.0000761892591823i

Ruby tan() Example 5

# import CMath library
require 'cmath'
x = CMath.tan(8)
puts x
# -6.799711455220379
