    Plane problem..

    Hello again i need some help for this problem:

    Find the plane equation if only is known that the point (3,4,-2) is normal projection of the coordinate start of that plane.

    tnx in advance

    I presume that <3, 4, -2> is a vector, not a point.

    What have you been able to do with this?

    Another thought. What do you mean by "coordinate start of the plane?"

    Okay. Well we can solve the problem in the form it is in only if we have a vector that is going to be normal to the plane we are trying to find and we have a point on the plane. We have the normal vector, but we don't have the point.
