y'' - y = e^(-t) - (2)(t)(e^(-t)) y(0)= 1 y'(0)= 2
Use Laplace Transforms to solve. Sketch the solution or use matlab to show the graph.
take Laplace
here we have y(0)=1 and y'(0)=2
take partial fraction
........................(1)
......................(2)
take s=-1
.
.
take s=1
.
.
put both constant in equation 2
.
.
.
compare coefficient both sides
.
apply Laplace rule
