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!!(adsbygoogle = window.adsbygoogle || []).push({});

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)/2

for which a particular solution x(t)=(t^{2}, -t) is known.
