vectors (but its not for math)

thing you need to know for solving vectors
When going in one direction then going to the opposite cancels each other. 
Example: you walk 5 m north then you walk 10 m south : position your 5m south

Wait wait wait that happen when you walk diagonally (basically a shortcut), think this through for a shortcut there has to be a long way right. that "shortcut" is the hypotenuse of a x and y

then is just simple SquareRoot (x2+y2)

find the adj and opp

adj = hyp*cosAngle

opp = hyp*sinAngle


opp & adj
is similar to x & y

Find the hypotenuse then it angle would be opp/adj tan-1  or adj/opp tan-1
