2. (a) Find the Laplace transform of f(t) = e^{2t}u(t - 1), where u(t - 1) denotes the Heaviside step function. (b) Find the inverse Laplace transform of F(s) = frac{e^{-pi s}}{s^{2} + 4s + 8}. (c) Use Laplace transforms to solve the ordinary differential equation frac{d^{2}x}{dt^{2}} + 4frac{dx}{dt} + 8x = delta(t - pi), where delta(t - pi) is the Dirac delta function, with initial conditions x(0) = 1, x'(0) = -2. Hint: Your result from part (b) may be useful.
