Transform the differential equation Ty" + 70y" - 343y' - 3430y = 7e-it y(0) = 0 y'(0) = 0 y"(0) = 1 into an algebraic equation by taking the Laplace transform of each side. Use Y for the Laplace transform of y, (not Y(s)). 7 s+9 Therefore Y 5+7 Taking the inverse Laplace transform we get y =\fTransform the differential equation 3y" + 4y' + y = sin(at) (0) =7 y' =5 into an algebraic equation by taking the Laplace transform of each side. Therefore v=|| 36483 Find the inverse Laplace transform f(t) = ~ {F(s)} of the function F(s) = S 8 8s fl=5 { i } S D help (formulas) s24+9 Consider the initial value problem y' +16y=32t, y(0)=6, y'(0)=09. a. Take the Laplace transform of both sides of the given differential equation to create the corresponding algebraic equation. Denote the Laplace transform of y() by (s). Do not move any terms from one side of the equation to the other (until you get to part (b) below). D D help (formulas) b. Solve your equation for '(s). Y(s) = L{y()} = | c. Take the inverse Laplace transform of both sides of the previous equation to solve for y(t). y(t) =[ |
