Question

if a vector×b vector =a vector. b vector then the angle is​

Answer 1

Answer:

For some vector spaces, we have the dot product A⃗ ⋅B⃗ (also known as the inner-product). In R3 , we also have the cross-product: A⃗ ×B⃗ .

Neither of these products are commonly written using the asterisk “*”. That means we do not know which product you mean.

For A⃗ ×B⃗ , we have that ∥A⃗ ×B⃗ ∥=∥A⃗ ∥⋅∥B⃗ ∥⋅sin(α) with α the angle between the two vectors.

For A⃗ ⋅B⃗ , we have that A⃗ ⋅B⃗ =∥A⃗ ∥⋅∥B⃗ ∥⋅cos(α) instead.
