Dot product and cross product vectors
WebMar 6, 2024 · The cross or vector product of two vectors a and b, written a × b, is the vector where n is a vector of unit length perpendicular to the plane of a and b and so directed that a right-handed screw rotated from a toward b will advance in the direction of n (see Figure 2).If a and b are parallel, a × b = 0. The magnitude of a × b can be … WebMar 28, 2016 · As for the dot product of two vectors, based on the law of cosines, you can interpret it as half the difference between the sum of their squares and the square of their difference: ‖ a → − b → ‖ 2 = ‖ a → ‖ 2 + ‖ b → ‖ 2 − 2 ( a → ⋅ b →). In other words, taking the vectors to be two sides of a triangle, the dot ...
