Can anyone direct me to a good discussion on the difference between the algebraic combination method and the scalar? Perhaps something that explains in specific mathematical terms what is going on, when, and why?I've read the User Guide (pages 6-23 and 6-24) and I understand that algebraic combines vectorially. But the scalar is confusing me. Here's the way I interpret what is being said about scalar: if you have a vector v magnitude at angle y and another vector x magnitude at angle z, the result after combining by the scalar method is a scalar of magnitude v+x? Or is the method only used for sets of information that are in the same direction?
