Webb2 nov. 2024 · Solution 1. If for given A → and B → the equality A → ⋅ C → = B → ⋅ C → holds for all vectors C →, or at least for a set of generators (say, a basis), then we can conclude that the two vectors are equal, otherwise we can't. I will try to make it plausible: If we take the standard basis { e → x, e → y, e → z } for vector ...

WebbThe cross product does not have the same properties as an ordinary vector. Ordinary vectors are called polar vectors while cross product vector are called axial (pseudo) vectors. In one way the cross product is an artificial vector. Actually, there does not exist a cross product vector in space with more than 3 dimensions.

WebbRemember that the dot product showed that two vectors are orthogonal to one another if the dot product between them equaled zero. So if I have vectors a, b, and cross product a x b, then a ∙ (a x b) = a ∙ [i (a 2 b 3 – a 3 b 2) - j (a 1 b 3 – a 3 b 1) + k (a 1 b 2 – a 2 b 1 )]
