Condsider the sequence of 1s.
And let Sn be the sum of the first n terms.
Then S1 = 1, S2 = 2, S3 = 3 and so on. As the number of terms becomes larger so does the corresponding S. As n tends to infinity, so does Sn.
A "proper" proof would be to show that if you give me any number X (however large), I can find a number k such that Sn is greater than X for all n greater than k.
A convergent series is a series whose terms approach a finite limit as the number of terms approaches infinity. In other words, the sum of the terms in a convergent series approaches a finite value. On the other hand, a divergent series is a series whose terms do not approach a finite limit as the number of terms approaches infinity. The sum of the terms in a divergent series does not converge to a finite value.
Because infinite means never ending - therefore there can never be a final answer, but sometimes an infinite series will converge to a finite answer. An example of one that results in an infinite answer should be fairly easy. Consider 1+2+3+4+5+6+.... Each number is bigger than the previous. But what about when each term is smaller than the previous. Look at this one: 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + .... Each term is 1/2 the previous term. As the terms are added, the sum of the series would look like this: 1/2, 3/4, 7/8, 15/16, 31/32,... Notice that each sum is half way between the previous sum and 1, but will never get to 1. We say this series converges to 1. Not every series, where the terms decrease, will converge to a finite number though.
You use a scientific calculator, or a logarithm table. The actual calculations are rather involved, and include adding up an infinite converging series. Eventually the terms of the series become small enough so that you can ignore them, but it is still too involved to do it on a regular basis.You use a scientific calculator, or a logarithm table.

It seems that you can't express that integral in terms of a finite number of commonly used functions. In the Wolfram Alpha site (input: "integral cos sin x"), you can find the first few terms of an infinite series expansion.
The summation of a geometric series to infinity is equal to a/1-rwhere a is equal to the first term and r is equal to the common difference between the terms.
The Nth partial sum is the sum of the first n terms in an infinite series.

There are an infinite number of them. The only one in lowest terms is 1271/50 .

It's not possible to 'complete' it, as it has potentially an infinite number of terms. The next five terms after those shown are: 10, 4, -3, -11, -20 . After those, there are only an infinite number more.

Not possible, summing an infinite series would take infinite time.
