Rules for cross product
WebbTaking, for example, two parallel vectors: the dot product will result in cos (0)=1 and the multiplication of the vector lengths, whereas the cross product will produce sin (0)=0 and zooms down all majesty of the vectors to zero. Another difference is the result of the calculation: Sal showed, that you're getting a plain SCALAR (number) as a ... WebbThe right-hand thumb rule for the cross-product of two vectors aids in determining the resultant vector’s direction. The orientation of a vector is the angle it makes with the x …
