  1. Sum A+B
    difference=A-B

    maginitude sum=ABcosTheta
    magnitude difference=ABcos(PI-Theta)

    setting them equal, then cosTheta=cos(PI-Theta)

    costheta=sinThetasinPI-cosThetaCosPI
    cosTheta=sinTheta+cosTheta
    which makes sense only if theta is zero or PI. The vectors A,B are colinear
