Homework Help: Orthogonal projection and reflection (matrices)

  1. Jan 27, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    reflection matrix = 2*projection matrix - Identity matrix

    3. The attempt at a solution
    Using the above equation, I get that B is the projection matrix and E is the reflection matrix.
    Can someone please verify if this is indeed the correct procedure?

    Your justification for the projection matrix might need some fleshing out.
    The equation for the reflection matrix justifies your choice of E if you can show that B is a projection matrix.
