hallo every body 

Please, I have a small problem in this program in Maple 18 at the end of the programme when i want to calculat the intgral given in variable (f2i)  i see this message and I can't calculate the integral 

Please what is the solution to calculate this integral?

The program in Maple 18 is below 

Thanks a lot
