2. Let C be the vector space of continuous functions and let V be the subspace spanned by the set E={cos(x), sin(x), cos(2x), sin(2x)}. Consider the linear transformation T : VV defined by T(f(x)) = f'(x), sending a function f(x) = V to its derivative. (a) Show that Ɛ is a basis for V. Hint: Plug in x = 0, π/2, π. (b) Find the matrix [T] of the transformation T with respect to the basis ε. (c) Show that [T] is a diagonal matrix. (d) Describe the linear transformation represented by the matrix [T]. That is, give L(f(x)) for the linear transformation LVV with [L] = [T]. [1234] -5 (e) Suppose f(x) = V has coordinates [f(x)] = with respect to the basis Ɛ. Compute the 100th π derivative of f. Your answer should be an element of V.
