The angle_with() is an inbuilt method in Ruby returns the angle between two vectors. The angle is always between 0 and π

Syntax: vec1.angle_with(vec2)

Parameters: The function accepts vector as parameter

Return Value: It returns the angle between two vectors

Example 1:






#Ruby program for angle_with() method in Vector
  
#Include matrix
require "matrix"
  
#Initialize the vector
    vec1
    = Vector[1, 2] vec2 = Vector[0, 1]
  
#Prints angle between two vectors
                          puts vec1.angle_with(vec2)

Output:

0.46364760900080615

Example 2:




#Ruby program for angle_with() method in Vector
  
#Include matrix
require "matrix"
  
#Initialize the vector
    vec1
    = Vector[1, 1, 0] vec2 = Vector[0, 1, 3]
  
#Prints angle between two vectors
                             puts vec1.angle_with(vec2)

Output:
