Hi, All,

Please see below:

> restart:
> with(DEtools):
> deq := diff(y(x),x,x) = A*exp(y(x)/vt);
> deq2 := diff(y(x),x,x) = A2*exp(y(x));

> #y := unapply(rhs(dsolve(deq,y(x))),x);
> y2 := unapply(rhs(dsolve(deq2,y(x))),x);

If I let two dsolve go, it gives error message for the second. However, commenting one and letting one go will always works perfectly. What's the problem, any bugs inside Maple. I tried in Classic Maple and Maple 10. same problem happend.



Please Wait...
