There is a widely used convention to provide the angles inradians, rather than in degrees, when dealing with trigonometric functions in general. Another convention is to consider that the positive angles are given by counterclockwise rotation, whereas negative angles are determined by clockwise rotation...
The leg across from the acute angle (an angle measuring less than 90 degrees) in the question is called the opposite side, while the leg touching the angle in the question is the adjacent side. Figure 2 shows an image of a right triangle. Figure 2: A right triangle. The formulas for ...
degrees(angle_in_radians) 58.462437107432784 And that angle of ~58.5 is the angle between the first and the third document of our document set. That is it, I hope you liked this third tutorial ! Cite this article as: Christian S. Perone, "Machine Learning :: Cosine Similarity for ...
