Additional exercise: Let V denote the vector space of smooth real-valued functions spanned by cos(x) and sin(x) and let L denote the linear transformation mapping V into V given by (L(f))(x) = f(x + y) for some fixed real number y. Find the matrix representation of L with respect to the basis {cos(x), sin(x)} of V. (Sorry about the minor notational differences from the problem specification in class; I don't know how to get the Greek alphabet and subscripts in HTML.)
