Cross Product of parallel vectors/collinear vectors is zero as sin(0) = 0. i × i = j × j = k × k = 0Either one can be used to find the angle between two vectors in R^3, but usually the dot product is easier to compute. If you are not in 3-dimensions then the dot product is the only way to find the angle. A common application is that two vectors are orthogonal if their dot product is zero and two vectors are parallel if their cross product is ... meet24 sign up The magnitude of the cross product is the same as the magnitude of one of them, multiplied by the component of one vector that is perpendicular to the other. If the vectors are parallel, no component is perpendicular to the other vector. Hence, the cross product is 0 although you can still find a perpendicular vector to both of these.We can use the form of the dot product in Equation 12.3.1 to find the measure of the angle between two nonzero vectors by rearranging Equation 12.3.1 to solve for the cosine of the angle: cosθ = ⇀ u ⋅ ⇀ v ‖ ⇀ u‖‖ ⇀ v‖.
