1. The problem statement, all variables and given/known data Vector A lies in the yz plane 63.0 degrees from the +y axis, has a positive z component, and has a magnitude 3.20 units. Vector B lies in the xz 48.0 degrees from the +x axis, has positive z component, and has magnitude 1.40 units. a) find A dot B b) find A x B c) the angle between A and B 2. Relevant equations dot product and cross product 3. The attempt at a solution What I am trying is to put them in unit vector notation like: A= axi+ayj so A= [3.20cos(63.0)]i+[3.20sin(63.0)] and then the same for vector B Then once I have those components I could easily do dot and cross product. My question is what does that "has a positive z component " have to do with anything? And is my setup correct?
