Question
Consider the differential equation
2y"+ ty'-2y = 14, y(0) = y'(0) = 0.
In some instances, the Laplace transform can be used to solve linear differential equations with variable monomial coefficients. Use Theorem 7.4.1.,
THEOREM 7.4.1 Derivatives of Transforms
If F(s) = L{ft)} and n = 1, 2, 3,..., then
L{"{t} = (-1)F(s),
ds"
to reduce the given differential equation to a linear first-order DE in the transformed function Ys) = Lly(t)}.
Solve the first-order DE for Y(s).
Y(s) =|
Then find y(t) = Z (Y(s)}.
y(t)%D
