The inverse of a function basically "undoes" the original. As a simple example, look at f (x) = 2x and g (x) = x/2. To see what I mean, pick a number, (we'll pick 9) and put it in f. f (9) = 2 (9) = 18.

First, we have just seen that T(→v) = proj→u(→v) is linear. Therefore by Theorem 5.2.1, we can find a matrix A such that T(→x) = A→x. The columns of the matrix for T are defined above as T(→ei). It follows that T(→ei) = proj→u(→ei) gives the ith column of the desired matrix.
