Explain why the value of [cos , sin ) *dot* [(cos(90+ ), sin(90+ )] is independent of .
^^ this is one of the problems I have due tomorrow. Problem is I don't even know what it's asking. independent? Are they saying that if you dot those, you can remove the theta and it still works? If this is what its asking I have no idea. i've been thinking about this for like half an hour and i think I'm missing something key? Please help =(
