title: calculate point given bearing, length and starting point
body: <p>I'm working on a 2d (x,y) plane. I have the initial point, a length and a bearing relative to north-aviation style bearing. Can someone help me calculate the end point of this line? I've seen a few different formulas but my maths isn't great so I'm not sure if they are correct.</p>
  
  <p>Thanks</p>
