Given 2 vectors, say x and y with a relationship of barXx-barYy (barX =1,0,0 and barY=0,1,0) calculations for the vector field in x and y plane are:
Magnitude = sqrt(x2+y2)
tails of vectors begin at input points (IE: if I choose 1,0 or 0,-1 etc) and the magnitudes are calcluated from these values with the equation above.
Question: how to find the angle of the vectors? If I use ones and zeros and the BarX dot BarYCos theta how to get theta? also barXdot BarY is zero making the whole thing zero?
