    What else comes up in P6 vectors other than the following:

    - Shortest distance between two lines.
    - Shortest distance between a point and a plane

    Do they ask about the shortest distance between a point and a line, how about a line and a plane, how about two planes?

    Help! Would like a comprehensive list of anything which may come up tomorrow in this area.

    Shortest distance between a point and a line comes up in p3 if i'm not mistaken. A line and a plane will always intersect if they are not parallel so you can just use the method you'd use for point and a plane, taking any point on the line...

    Need to be able to

    determine whether a line lies in a plane, intersects a plane and find the p.o.i when it exists

    find line of intersection of 2 non-parallel planes

    find the perpendicular distance from a point to a plane and from a pointr to a line

    find the angle between a line and a plane and the angle between 2 planes

    find the shortest distance between 2 skew lines

    Area of the parallelogram formed from the two vectors rings a bell as well. As does finding the angle between two planes (though that's pure 3 on my course, it's synoptic so may come up again).
