Use the Laplace transform to solve the following initial value problem: " - y' - 20y= 0,
(1) First, using Y for the Laplace transform of y(t), i.e., Y = L(y(t)).
find the equation you get by taking the Laplace transform of the differential equation to obtain
(2) Next solve for Y =
A
(3) Now write the above answer in its partial fraction form, Y
+

=
y(0) 9, y'(0) = 9
0
(NOTE: the order that you enter your answers matter so you must order your terms so that the first corresponds to a and the second to b, where a <b. Also note, for example that -2 < 1)
Y =
(4) Finally apply the inverse Laplace transform to find y(t)
y(t) =
