3 Given that the Laplace transform of x is F(3) 1
derive the
Laplace transform of xl without using the integral definition
4 Use the Laplace transform to volve each of the following equations.
(a) f(x) + f(x) = x where f(0) = 0
(b) f(x) -x) = where f(0) = -1
(c) '(x) + 48(x) + 4) where 0 = 0 and (0) - 0
(d) 48" (x) - 9f(x) = -18 where f(0) = 0 and f(0) 0
3 Show that if F() - )
xxx then:
(a) () F() L()) m () - 110
Use part (a) to find
(b) 01 Lsin 2x) ir 11x cos3x)
