[Axiom-mail] newbie

Hi,

I am a newbie in Axiom. I am trying to solve a differential equation as given in the page 119 of the axiom manual. I type in exactly what is given in the manual but  I get:

(1) -> y:= operator 'y

   (1)  y
                                                          Type: BasicOperator
(2) -> deq:= (x**2 + 1)* D(yx,x,2) + 3*x* D(yx,x) + yx = 0

   (2)  yx= 0
                                            Type: Equation Polynomial Integer

What am I suppose to do?

Many thanks for the help.

Best Regards
