Ruby CMath atan() Method with example
atan() method is CMath class which is used to returns the arc tangent of the given value.
Syntax: Math.atan(z)
Parameter: Here, z is the value whose arc tangent is to be calculated.
Returns: This method returns the arc tangent value of the z.
Example 1:
# Ruby code for atan() method require 'cmath' # Initializing value a = 0 . 3584 b = 2 # Printing result puts "atan value of a : #{CMath.atan(a)}\n\n" puts "atan value of b : #{CMath.atan(b)}\n\n" |
Output:
atan value of a : 0.34413842830780517 atan value of b : 1.1071487177940904
Example 2:
# Ruby code for atan() method require 'cmath' # Initializing value a = 0 b = - 0 . 247 # Printing result puts "atan value of a : #{CMath.atan(a)}\n\n" puts "atan value of b : #{CMath.atan(b)}\n\n" |
Output:
atan value of a : 0.0 atan value of b : -0.24215314674687552
