Explain how you would determine how much error there is between a vector addition and the real results.
can you help me please?
i think their is no error vectors are perfect
Between a vector addition and real results? Depends what you mean by "real results", if they're based on the same data, there is no error, if you mean like experimental data, then, give us that and I'll have to see.
I'm sorry here disregard that last question sing what you have determined to be the best method, develop a unique example (not posted on the discussion board by anyone else) and calculate the resultant displacement between two points when there are two legs or distinct parts to the trip. Include the displacement of each leg of the trip as well as the resultant displacement of the entire trip.
Err, if I understand your question, you can add both trajectories' vector path and then subtract both end points from each other to get the resultant vector between the paths.
