I wont post the actual problem with numbers, I just need some direction. My teacher never went over this part of the webwork in class, and we havent touched on it in physics either. "a" and "b" are both 3D vectors. 1.) I am supposed to find the component of "b" along "a" 2.) I am supposed to find the projection of "b" onto "a" 3.) I am supposed to find the projection of "b" orthogonal to "a" If somewhat could shed some light on what im actually doing, and maybe give me some direction it would be greatly appreciated.
