Hi,
can you please solve this and show work.
Let W be a 2-dimensional subspace of R'. Recall that the function T:X → projw X, mapping any vector to its projection onto W is a linear transformation. Let A be the standard matrix of T. a) Explain why Ax = x for any vector x in W. Show that Null(A) = Wt. What is dim(Null(A))?| (Hint: Recall that, for any vector x, X - projw x is orthogonal to W.)...
