1. The problem statement, all variables and given/known data To find the component of one vector A along another vector B. 2. Relevant equations Components are A(cos theta) and A(sin theta) 3. The attempt at a solution What I tried was to consider the vector B as a "pseudo x axis" and draw a subsequent "pseudo y axis". Then, using angle between them, I found A(cos theta). I'm not sure this is the correct method, so could someone point out how correctly to find it?
