WebThere are numerous ways to multiply two Euclidean vectors. The dot product takes in two vectors and returns a scalar, while the cross product [a] returns a pseudovector. Both of these have various significant geometric interpretations and are widely used in mathematics, physics, and engineering. WebThe cross product of two (3 dimensional) vectors is indeed a new vector. So you actually have a product. It is still a bit of a strange product in that it is not commutative. x → × y → isn't the same as y → × x → . x → × y → = - y → × x → Now about division. If you have two real numbers x and y ≠ 0, we say that x y = z exactly when x = y z.

WebFeb 5, 2024 · 1 Answer. It looks like you're trying to make a, b, and c refer to A [0], A [1], and A [2], but that is not what happens. shadow the global variables A and B, and initialize those two vectors with {0,0,0} (because a,b,c,x,y, or z are never set).
