WebThey can be multiplied using the "Dot Product" (also see Cross Product). Calculating. The Dot Product is written using a central dot: ... (ordinary number) answer, and is sometimes called the scalar product. But there is also the Cross Product which gives a vector as an answer, and is sometimes called the vector product. 3036, 3037, 3030, 3031 ...
Web3: Cross product The cross product of two vectors ~v = hv1,v2i and w~ = hw1,w2i in the plane is the scalar v1w2 − v2w1. To remember this, we can write it as a determinant: take the product of the diagonal entries and subtract the product of the side diagonal. " v1 v2 w1 w2 #. The cross product of two vectors ~v = hv1,v2,v3i and w~ = hw1,w2 ...
