Yes, that's true, I need to add β as the 3rd parameter when define T, perhaps it will help. Thank you acer.

I find out the solution, and here it is: http://www.maplesoft.com/support/faqs/detail.aspx?sid=34041&pid=11.

Is Maple 13.01 compatible with MapleSim 2? I cann't use MapleSim 2 now for the version reason and how can I fix it?

Indeed, the example you give is just opposite to mine, but more often the case is Maple takes much more time, especially when I want to get a precise symbol number answer. I don't know whether my PC has something that is not suitable for calculating. Another case is to find the ith prime number using ithprime(i), however when the argument is larger than 10^7 or 10^8 there is no response on my PC within 10 minutes. There is really a extraordinary difference indeed. Dust you are, to dust you shall return.

Of course this summation has a convergence range, it is abs(x)<1. It seems that Maple could not deal with those summations that the inner ones link to the outer ones. But if I could not seperate them to sum indices themselves, how can I solve those sums? Dust you are, to dust you shall return.
