This should be simply (x-1)/x.

There's only one term in the summation, since n runs fom 1 to 1.

And with n being 1, the multiplication contains also only one term, since k runs from 1 to n=1.

So with k being 1, the one term is (kx-1)/kx, simplifies to (x-1)/x.

Regards,

Luc

And that is the last line from the symbolic evaluation above

But ok, I understand your point that you do not require mathcad for this. However, when you try to evaluate the expression in M15 you get

and probably this was Loi Le's point in posting the thread.

A sum from 1 to 1 can be omitted as can a product from 1 to 1. So you don't need Mathcad to get x/(x+1), right?
