    How Do You Find the Closest Point to a Vector on a Line?

    <img src=http://img535.imageshack.us/img535/6664/vectordistance.png> That is my own drawing. I made up the placement of B.

    How Do You Find the Closest Point to a Vector on a Line?

    Here is a picture of what, I think, is going on: http://imageshack.us/photo/my-images/535/vectordistance.png/ I'm aware of what a vector is (took AP Calculus BC (5), and Physics B (5)), which is why I don't understand what this question is even getting at.

    How Do You Find the Closest Point to a Vector on a Line?

    I have a question though. Can you/someone draw out what is going on? Wouldn't the answer always be the the tail (0,0), because presumably the other vector, B, is also starting at the origin. Thus the two vectors are starting on top of each other?

    Infinitely long prism is sliced

    Homework Statement What happens when an infinitely tall vertical rectangular prism consisting of all (x,y,z) with x between a and b and y between c and d is cut by a non-vertical plane z = px + qy + k? What are the possible shapes of the slice? Homework Equations I don't know...no...
