Hi everybody,

I'm trying to solve  exact ODEs with first order and complex coeff.

I solve the system by seperate the real part and the im.part and then solved it numeric. no problems with that.

I would like to compare the exact solutions with the numerical one and use the solutions in formula tha in double integral.

My question how can i get exact solutions by maple( i tried but maple give me message that  can't alloc memory).
