Homework Statement
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
Homework Equations
Dot product?
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?
