Additional Problem 2: Give one example of functions f and 9 such that E {f(t)9(t)} 79 E {f(t)} C {905)} Note: I recommend constant or exponential functions, but most guesses should work Additional Problem 3: Find r, {132} (a) Using the denition. I recommend using tabular integration, see the end of the 6.1 lecture. Assume the terms at 00 are 0 (b) Using (152)\" = 2 and taking Laplace transforms on both sides, using the important formula, and solving for E {t2}
