Question:
(a) Assume that Theorem 7.3.1 holds when the symbol a is replaced by ki, where k is a real number and i2 = -1. Show that ℒ{tekti} can be used to deduce
(b) Now use the Laplace transform to solve the initial value problem x'' + ω2x = cos ωt, x(0) = 0, '(0) = 0.
Theorem 7.3.1
If ℒ{f(t)} = F(s) and a is any real number, then
