Repost. Sorry if things aren't clear. Here are the given using latex A=\begin{pmatrix}4 & 1/3\\ 9 & 6\end{pmatrix} F(t)=\begin{pmatrix}-e^t\\ e^t\end{pmatrix} ##Xc=c1\begin{pmatrix}1\\ 3\end{pmatrix}e^3t + c2\begin{pmatrix} 1\\ 9\end{pmatrix}e^7t## I'm having trouble finding the...

Hello guys, I need help solving this problem. Find the particular solution using method of undetermined coefficients: X'=AX + F(t) A= [4 ,1/3] <-- 1st row [9 , 6] <-- 2nd row F(t) = [-e^t,e^t] The complementary function is Xc=c1[1,3]e^(3t) + c2[1,9]e^(7t) Any help would be...
