Now how would you describe the graph of this function when say N=5, N=10, and N=100? And what does it mean does the graph confirm the limiting behavior of the integral's value?

(A) y =x+3 (B) correct (C) correct

But how can you tell the limit?

But how did you arrive at "as N gets big this looks like e^x(-NcosNx)/N^2?????

is it because every interval of one the integrals approach 1?

I meant to say zero

But then would this confirm the limiting behavior of the graph because at every interval up to infinity it would approaching zero?

Yes I have, but I don't understand why the integral would go to zero. And the description of the interval.

1. Why might a profitable motel shut down in the long run if the land on which it is located becomes extremely valuable due to surrounding economic development? 1a. What kinds of costs are involved in making a decision to shut down?

Thank you Steve

alright, thanks Reiny!

nevermind, I got it. It's convergent because the definite integral is = 3!

so I realized it's not using the derivative that we find if a sequenec is ascending/descending, but rather comparing the series. Nonetheless, the sequence is still descending.

Found it, the answer is S=3

but if I put n = 1 in both I get =2 for the first and =1.8 for n+1. Or is that not how I go about doing it?

Ok I see, I was just adding the same fractions on every line instead of just adding the answer from the previous. Thanks Steve!

so the upper bound is 1, since it converges, right?

Because I thought that if it decreases it'll eventually get lower than 1. What is the definition of lower and upper bound, I don't get that part.

Oh, 2 would be the upper bound? Because it can't go higher than 2?

or rather it starts off at 2

Ok so lower bound is the lowest achievable value, so upper bound will be the highest, right?

Okay I get it now!! Thanks a lot Steve :)

so what's the best way to find that number? would it be putting n towards infinity or 0?
