I would like solved System of ODE with periodic coeffs. as this:
DSolve[{Derivative[1][x1][t] == Cos[t]*x1[t] + 1.5*x2[t],
Derivative[1][x2][t] == 2.1*x1[t] + 2.3*x2[t], x1[0] == 1, x2[0] ==
0}, {x1[t], x2[t]}, t]
I wish obtain the analitycal solution. I have tested with DSolve but
doesn`t work (Even using Rationalize, giving numeric values of initial
conditions,i.e.: a =1).
Any help (package, etc.) Thanks
