Hi

I used maple to solve a 4th order ode:

ode:=(h2(x)*diff(eta1IItrans(x),x$4)+diff(h2(x),x)*diff(eta1IItrans(x),x$3)+(1/(g1*h1))*((w^2)*(h1+h2(x))*diff(eta1IItrans(x),x$2)+(w^2)*diff(h2(x),x)*diff(eta1IItrans(x),x)+(w^4/g)*eta1IItrans(x))=0);

avec h2:=x->h2I*exp(d*x):

I have 2 questions:

-I can get a solution only with precise values of parameters (g, h, d etc...) but I would like a literal one.
