Homework Help: Please help with vectors and points

  1. Jan 30, 2006 #1
    Hi, I'm Xairylle and I need a little help with this. I think it's kind of basic electromagnetics stuff but I don't know how this goes given that all I've got is a problem nothing else. I am so sorry, I didn't see this room in the forum earlier so I made a post in the General Engineering section. Is that a bad thing? If so, I am sorry.

    1. Express each of the given points into its equivalent vector
    a) A(2,1,-5)
    b) A(1,4,6) B(5,-3,0)

    2. Find the lengths of the medians of the given triangles ABC
    a) A(2,1,3) B(3,-1,-2) C(0,2,-1)

    I need solutions and answers since I really can't understand. Please help if it's not too much trouble. Thank you.
