Dot product of normal vectors

WebDec 8, 2024 · To determine a normal vector, we set the dot product between the vectors equal to zero. The equation for the dot product is: The equation for the dot product is: In the equation, vector b is the ... Web1. The norm (or "length") of a vector is the square root of the inner product of the vector with itself. 2. The inner product of two orthogonal vectors is 0. 3. And the cos of the angle between two vectors is the inner product of those vectors divided by the norms of those two vectors. Hope that helps!
