WebSo in that sense you could define a type of division of vectors. However, again there are some problems with vectors. When we divide by a real number y, we can also consider this as multiplying by the inverse of y, that is, y − 1. The inverse of y is that unique number y − 1 such that yy − 1 = 1. Web8 nov. 2024 · One can clearly come up with a 1:1 correspondence between 2D vectors and complex numbers. Let v = [ x y] f: R 2 → C f ( v) = x + i y This function is injective and surjective so it is a bijection. However, this function doesn't preserve nice properties. Consider u = [ a b] f ( v) ⋅ f ( u) = x a − y b + i x b + i x a ≠ x a + y b = v ⋅ u

WebWe also recall that a 2D vector can be expressed in terms of fundamental unit vectors ⃑ 𝑖 and ⃑ 𝑗, which are defined by ⃑ 𝑖 = (1, 0), ⃑ 𝑗 = (0, 1).. Starting from the component form of a vector, we can apply vector addition and scalar multiplication to write (𝑎, 𝑏) = (𝑎, 0) + (0, 𝑏) = 𝑎 (1, 0) + 𝑏 (0, 1) = 𝑎 ⃑ 𝑖 + 𝑏 ⃑ 𝑗.
