out equation is

we see that the numerator is going to be a finite quantity as it remains 1 or -1 to the power n

but upon seeing the denominator we came across that

the term

which shows us that denominator is growing to infinity

hence ,

where is a constant and the summation of the series is =0

#### Explanation:

Set

So we have

Hence

Since now we have the [What is the Taylor series of

In particular
