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!! 1. The problem statement, all variables and given/known data Find with the aid of D’Alembert’s reduction principle the Fundamental system of the ODE system. x1(t)'= x1(t)/t - x2(t) x2(t)'= x1(t)/t2+ 2x2(t)/2 for which a particular solution x(t)=(t2, -t) is known.
