Homework Help: Projection Proof

  1. Oct 7, 2008 #1
    1. The problem statement, all variables and given/known data How would i go about solving Proju(Proju(v))=Proju(v) Just a note Proju(v) means the projection of v onto you

    2. Relevant equations

    3. The attempt at a solution how would i go about solving this is mathematical terms, it is obvious when you do it geometrically but im just not sure how i would go about doing it mathematically
