I am trying to figure out how to get the heading of a wind with U and V components, using a Vector Triangle. I have been trying to study the bottom of http://www.aprweather.com/pages/wind.htm and still just don't get how to actually get the heading.
Given a U and a V componenent, where V is the Y axis and U is the X axis, how could I get the heading (in 360 degrees) of a line where U or V can be a positive or negative number?
