WebThe dot product as projection. The dot product of the vectors a (in blue) and b (in green), when divided by the magnitude of b, is the projection of a onto b. This projection is …
WebSolution: Using the component formula for the dot product of three-dimensional vectors, a ⋅ b = a 1 b 1 + a 2 b 2 + a 3 b 3, we calculate the dot product to be a ⋅ b = 1 ( 4) + 2 ( − 5) + 3 ( 6) = 4 − 10 + 18 = 12. Since a ⋅ b is positive, we can infer from the geometric definition, that the vectors form an acute angle.
