Finding Equation of line of intersecting planes

  1. Oct 2, 2010 #1
    Hey guys,

    I just have a general question, How would you find the equation of a line with just the equations of the planes intersecting. I know for the direction vector it would be the cross product, but for the other part of the equation r=ro +tv, the ro part i do not know how to find.

    [tex]r_0[/tex] is any single point on the line of intersection, which means you just need to find any one point that lies on both planes.
