How to simplify (a-b)x(a+b) Vectors Cross Product - YouTube
Webb• The dot product of two vectors A·B in this notation is A·B = A 1B 1 +A 2B 2 +A 3B 3 = X3 i=1 A iB i = X3 i=1 X3 j=1 A ijδ ij. Note that there are nine terms in the final sums, but only three of them are non-zero. • The ith component of the cross produce of two vectors A×B becomes (A×B) i = X3 j=1 X3 k=1 ε ijkA jB k. Webb7 jan. 2024 · Let ( a, b) ∈ ( A × B) ∩ ( B × A), then we have that a ∈ B and b ∈ A. This gives a, b ∈ A ∩ B. Since A ∩ B = B ∩ A, we derive ( a, b) ∈ ( A ∩ B) × ( B ∩ A). Thus we have shown that ( A × B) ∩ ( B × A) ⊆ ( A ∩ B) × ( B ∩ A). It is now your turn to show that ( A × B) ∩ ( B × A) ⊇ ( A ∩ B) × ( B ∩ A).
