(b) (9 points) Solve the initial value problem y00 + 16y = ?(t?1) y(0) = 0, y0(0) = 0 where ?(t?1) is the Dirac delta function at t0 = 1. (c) (3 points) Let yk(t) denote your solution from part (a) and let ˆ y(t) denote your solution from part (b). Show that when t = 2lim k?+?yk(2) = ˆ y(2)Just answer question B and C is ok.
