Thinking back to geometry and linear algebra, a normalized vector quantity represents a direction. Two vectors can be said to be similar if the angle between the vectors is very small (If the angle is 0 degrees, they are equal, if the angle is 180 degrees they are exact opposites). It is possible to determine the angle between two vectors by using the Euclidean dot product formula. A B = ||A||||B|| cos(0) Therefore, cos(0) = curyilira A. B ||A||||B|| We don't really need the angle - using the cosine of the angle is good enough. A value of 1 means the two vectors are identical. A value of -1 means the vectors could not be more different. Write a method to calculate the cosime similarity of two vectors Thinking back to geometry and linear algebra, a normalized vector quantity represents a direction.
