Show that

converges to some real number.

The problem hints that I'm supposed to use the fact that

converges uniformly on [0,1], which I've already proved.

I can't figure out how to connect these two facts at all... any help?

Let's use your hint.

Because of the uniform convergence, the sum is continuous on . Furthermore, you may integrate term by term on . Note also that . We get:

.

The important thing is that the right-hand side is finite.

The above shows (means) that has a finite limit as .

However, this partial sum can be rewritten as ... - Apr 8th 2010, 02:02 PMpaupsers
