1. The problem statement, all variables and given/known data E = [axhat(A(x+y)) = ayhat(B(x-y))]cos(wt) Determine the relationship between A and B 2. Relevant equations I don't know if there are any. 3. The attempt at a solution I've expanded the problem and reduced it to E = cos(wt)[x(A+B)axhat + y(A-B)ayhat] I was going to take the real component and convert to the frequency domain to try to manipulate the cosines but I don't know if that's the right step. If someone could just get me started or point me in the right direction I think I could figure it out. Not looking for someone to do this for me.
