## Main Question or Discussion Point

Hey guys, I'm stuck on this problem! I have no idea how to even go about solving it. I tried searching the net for D'Alembert's principle but nothing was helpful. Any suggestions on how to go about solving it will be much appreciated!!

Find with the aid of D’Alembert’s reduction principle the FS of the ODE system.

x

x

for which a particular solution x(t)=(t

Find with the aid of D’Alembert’s reduction principle the FS of the ODE system.

x

_{1}(t)= x_{1}(t)/t - x_{2}(t)x

_{2}(t)= x_{1}(t)/t^{2}+ 2x_{2}(t)/2for which a particular solution x(t)=(t

^{2}, -t) is known.
