# How do you know if #sumn/(e(n^2))# converges from 1 to infinity?

We can rewrite the sum as:

Thus we have a scalar multiple of a Divergent series, thus we end up with a Divergent series.

so:

Proof of the divergence of the Harmonic Series.

It seems possible that the question was supposed to be about the series:

If this is the series we're interested in, use the integral test.

So

which converges.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Does #a_n=(n + (n/2))^(1/n) # converge?
- How do you find the limit of #(e^(3x) - e^(5x))/(x)# as x approaches 0?
- How do you determine whether the sequence #a_n=(-1)^n/sqrtn# converges, if so how do you find the limit?
- How do you find #lim (1/t+1/sqrtt)(sqrt(t+1)-1)# as #t->0^+# using l'Hospital's Rule?
- How do you use the integral test to determine whether #int e^(-x^2)# converges or diverges from #[0,oo)#?
