1. The problem statement, all variables and given/known data The following are all vectors: A = <2, 1, 1> B = <1, -2, 2> C = <3, -4, 2> Find the projection of (A + C) in the direction of B 2. Relevant equations Dot product? 3. The attempt at a solution I was not sure what the meant in this question. I added A and C and I got (A+C) = <5, -3, 3> Then I did (A+C)dot(B) and I got that equal to 16 I was also thinking of dotting (A+C) with the unit vector of B?
