    Undergrad What is the composition of T and T in terms of linear transformations?

    The length will remain the same, as the projection of the vector v on u is the vector itself. So I suppose to describe the composition I would just write out the original projection formula?

    Undergrad What is the composition of T and T in terms of linear transformations?

    ( (u.[( (u.v)/(u.u) )u])/u.u ) u Is that all?

    Undergrad What is the composition of T and T in terms of linear transformations?

    Sorry, I don't see little boxes. Maybe a computer issue but its just: ToT (I'm not sure if this is T dot T or if the larger circle represents something else) Thanks!

    Undergrad What is the composition of T and T in terms of linear transformations?

    Let u (not equal to 0) be a vector in R^2 and let T: v --> proju(v) 1. Show that T is a linear transformation. 2. Describe the composition T  T. 3. If ~u = [1,−1], find the standard matrix for T. I'm good with 1 and 3, but I'm not sure what 2 is asking. Excuse the poor notation...
