Compute the even and odd components of the signal: x(t) = (cos(4t) + sin(4t)). Show your work and put a box around your answer. (2 Marks) Compute either the average power or the total energy (which ever is most appropriate) for the signal x(t) = cos(4nt) (3u(t + 3)-3u(t-3)) where u(t) is the unit step function. Show your work and put a box around your answer. (3 Marks) Construct the signal x (t) = {2t-3 -1
