3. Let V be the span of the functions $\cos(2x)$ and $\sin(2x)$. The sets $\alpha = \{\cos(2x), \sin(2x)\}$ $\beta = \{\cos(2x) + \sin(2x), \cos(2x) - \sin(2x)\}$ are bases for V. Let $L = D^2 + 1$. (a) (6 points) Compute the change of basis matrix $P = [I]_\beta^\alpha$ and its inverse. (b) (3 points) Compute the matrix of L with respect to $\alpha$. (c) (3 points) Compute the matrix of L with respect to $\beta$. (d) (2 points) Find $[3\cos(2x) + 4\sin(2x)]_\beta$. (e) (1 point (bonus)) Describe geometrically what L does to V.
