Dot Product vs Cross Product : What

WebDefining the Cross Product. The dot product represents the similarity between vectors as a single number: For example, we can say that North and East are 0% similar since ( 0, 1) ⋅ ( 1, 0) = 0. Or that North and Northeast are 70% similar ( cos ( 45) = .707, remember that trig functions are percentages .) The similarity shows the amount of one ... WebSep 17, 2024 · The dot product of two vectors x, y in Rn is x ⋅ y = (x1 x2 ⋮ xn) ⋅ (y1 y2 ⋮ yn) = x1y1 + x2y2 + ⋯ + xnyn. Thinking of x, y as column vectors, this is the same as xTy. For example, (1 2 3) ⋅ (4 5 6) = (1 2 3)(4 5 6) = 1 ⋅ 4 + 2 ⋅ 5 + 3 ⋅ 6 = 32.
