Dear Physics forum subscribers,(adsbygoogle = window.adsbygoogle || []).push({});

I currently have a problem whereby I need to combine the magnitude and direction of a vector (in my case a length in mm, and angle in degrees, although can be converted to radians) into one single figure, that will not repeat itself for all lengths up to 5 mm within 360 degrees. This is for use in Statistical analysis using correlation coefficients to test against one of my output variables.

I have tried a couple of methods, however am now unsure as to whether this is mathematically possible? Additionally I have failed to find any literature that has attempted this.

I've tried to keep this message as simple as possible, however if you need any more information as to methods I've tried or more information on my study please let me know.

I am a Sports Biomechanist and not a pure Physicist, so do excuse me if I have posted this within the wrong forum.
