Homework Help: Vector calculus

  1. Feb 9, 2006 #1
    I have a point in (x,y,z) and a plane in the form Ax+By+Cz=D and I need to find the distance between the point and the plane. I tried using parametrics and cross products, but I couldn't figure it out. Thanks

    Can you find a vector that is perpendicular to the plane?
    Once you have that, can you find a line that is perpendicular to the plane, and goes through the point?

    the plane equation N.P-D=0 may be more usefull to you where N is the normal of the play. and D=N.P0, p0 a point given on the plane. Think how you'd get N from the equation you gave.
