Would anyone be able to help me integrate ones like the following: Int(1/exp(eta)*eta*hypergeom([1, 1, 1],[2, 2, 2],eta),eta); I've tried using convert, simplify, etc. but nothing works. Many thanks, Sandra

1. I have a third order PDE with boundary conditions. I try and solve numerically but Maple 9 returns the above error ... Error, (in pdsolve/numeric) unable to handle elliptic PDEs. Would anyone be able to help? 2. If I transform this PDE into an ODE, it returns that there is a "removable singularity at x=0". How do I solve knowing this? Many thanks for any help. Sandra
