Ruby | CMath acos() Method
acos() method is CMath class which is used to returns the arc cosine of the given value.
Syntax: Math.acos(z)
Parameter: Here, z is the value whose arc cosine is to be calculated.
Returns: This method returns the arc cosine value of the z.
Example #1:
# Ruby code for acos() methodrequire 'cmath' # Initialize value a = 0.3584b = 2 # Printing result puts "acos value of a : #{CMath.acos(a)}\n\n"puts "acos value of b : #{CMath.acos(b)}\n\n" |
Output:
acos value of a : 1.204242852965772 acos value of b : 0.0+1.3169578969248164i
Example #2:
# Ruby code for acos() methodrequire 'cmath' # Initialize value a = 0b = -0.247 # Printng result puts "acos value of a : #{CMath.acos(a)}\n\n"puts "acos value of b : #{CMath.acos(b)}\n\n" |
Output:
acos value of a : 1.5707963267948966 acos value of b : 1.8203794286756558
