We are using a smart phone app to add vectors; once we get the resultant angle, we need to determine what direction the vector is based on the compass. Can someone easily explain how to do this? Example: Using the app, we input a 2 knot current toward 230 degrees and a 0.7 knot wind speed from 320 degrees. The resultant values are 2.119 magnitude, angle of 30.710 degrees and a vector of <1.82, 1.08> What we need is an EASY way to compute the compass direction from the 30.710 angle. I know this has something to do with what quadrant the vector resides in and it involves adding or subtracting 180 or 360 degrees, but I don't have a physics background and am looking for an "easy" and repeatable means of converting. Thank you in advance for any assistance. I can provide additional information via email if required.
