this gives the formula cos theta = barV dot bar U / the magnitudes of vu. as mentioned before this returns a value of zero whether the y component or the x component is zero. so this means each vector with a zero Y component has a 90 degree vector and this cannot be.

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...
