Vector cross product with coefficients

  1. Oct 1, 2012 #1
    Anyone know how would I simplify a cross product where the two vectors have coefficients? For example [itex](x/(y^3))\bar{r}[/itex] X [itex](x/(y))\bar{L}[/itex]

    Just pull the coefficients out.

    In other words, [itex](a\vec{u})\times(b\vec{v})= ab (\vec{u}\times \vec{b})[/itex].
