Ok, my question is, if you have 2 vectors added together a+b, could the magnitude of the resultant change if u subracted a-b? say a was any magnitude at 0 degrees. and b was any magnitude say 170 degrees. if u subtracted b it would go opposite direction southeast making the resultant much larger since it makes obtuse angle right? I might be completely wrong on this.(adsbygoogle = window.adsbygoogle || []).push({});

thank you in advance.
