Homework Statement
In this problem, we will solve the initial value inhomogeneous differential equation in two steps.
y''+4y=2x*e^(3x) y(0)=0 y'(0)=0
1.) First determine yp the particular solution to the differential equation.
2.) Next determine y=yc+yp the complete solution to the differential equation.
The Attempt at a Solution
the roots i got were 0 and -4.
i did y''+4y=0
'equivalent' to: r^2 + 4r = 0
dont know what to do next. usually we'll go onto the yc part but idk what its supposed to look like. the notes suggest that equation will have sin(something) and a cos(something)
help please! i should be able to do part 2 on my own; but we'll see
