Use Dot Product to Find the Angle between Two 3D vectors

The objective of this video is to explain the use of the dot product to find the angle between two 3D vectors U and V starting from the formula U.V = |U| . |V| . cos(theta) where U . V is the dot product calculated using the components of U and V. |U| and |V| are the lengths of the vectors U and V, and theta is the angle between them. more at: www.analyzemath.com/high_school_math/grade_12/scal_cross.html More math videos at https://www.analyzemath.com/math-videos.html.
