you&#x27;re asked Seamus, function here or sequences so but a and B some sequence of real numbers limit as n approaches. Infinity of sequence is l and those that f is a function which is continuous it l find that every member of sequence you want to show that the limit as n approaches infinity of today and is equal to Fidel And we have personal Yeah, since it is a your function, that means that said, mum, Berries they end so sequence, uh, real numbers. And what&#x27;s Absalon Me? Positive real number. He&#x27;s in U S. A. L. You can find a belt 3 to 0 such that X minus fell is less than then We have the FX, my second bells That&#x27;s absolutely and also flying natural number in such that it is greater than then we have it a n minus fell. Plus it&#x27;s a long once stated that salon I take This data is also a positive here in London, Then every day in minus no, we have it X or is greater than then. Do you have that a minus? L less don&#x27;t. It&#x27;s using They and his ex in the previous statement have that follows that a my s l going to be less than excellent. So it follows that Corbyn very a limit as to infinity. Oh, they end to Bill, which isn&#x27;t equal to of okay as approaches infinity of a

Chris Trentman · Answer

you&#x27;re asked through sandwich here, um, or sequences. So we&#x27;re getting that. I am the end. CNN are all sequences of numbers we have The day ends Lesson Vienna&#x27;s Western for CNN or oh, and greater than end of some any natural numbers. And he had the limit, isn&#x27;t it? Purchase infinity? I am CNN. Help you want to show a limit is an approaches Infinity of sequence PM is also so take up salon to be some arbitrary, positive real numbers and find to natural numbers. Then one and Internet remembers such that a n minus spells going to be read in that salon world engraved on one CN minus l you know, Salon girl and greater than two now take and three maximum Oh, and and one 10 to This is an element of natural numbers and we have that Yeah, and is greater than three and e n minus. L we have personal have been from end raising capital end It&#x27;s and slash or bien open CNN you have in mind is there even that&#x27;s on and we happen. CN minus create an excellent instead of very next should be Western. So you have that the end minus Ellis would be greater than or equal to a n minus. L last CN minus l You know that A. M minus l It&#x27;s going to be great and are equal to the opposite. The absolute value of a N minus l which is equal to equal to the richer than Maybe that&#x27;s a lot. And we have been seeing Miner sells on the gets a value in my cell. One less than salon between the B in my cell lies between negative salon. That&#x27;s a long so we have that absolute value of being one herself won&#x27;t be less than Absalon and this greater than and three in there for follows that the limits as a purpose. Infinity Yeah, people to help.

we want to prove they&#x27;re too. Which was the sandwich them. So the sandwich, Arum says. If a N is less American to be in this lesson, good to see him eventually for some large enough values of little. And it&#x27;s things that way as well as if we have the limit of opinion and CNN, as in Vincent, any both perching. Then we have that the limit, as in a purchase. Vivica Bian is l also all right, so let&#x27;s go ahead and start the proof. So since we&#x27;re trying to show that something convergence, remember, the first thing we want to start with is let infinity be absolute, be greater than zero. And now we want to go through the process of showing that there exists some capital in such that any time little inn is greater than capital in, we will have that being minus l absolute value will be less than absolute. So kind of keep that in mind. What? We&#x27;re going through the steps for this. All right, So when a person is reading zero well over here, since these two will converge to Elle, that will tell us so there exist the capital, which will call Capital in one Such that Excellent. Just write it out. Such that Yeah, little n is greater than capital in one. Then we have the absolute value of a N minus. L is less than absolute. And also we know that there exists some capital into such that if capital in her little inn is strictly larger than capital in two, then absolute value of CNN Miter cell is also less than absolute are now What I&#x27;m going to do is let this capital in equal to the max. Oh, Capital in one and capital in two. So if we have this, then the previous line here will hold in each case for this new value of n. That&#x27;s why I&#x27;m just choosing and to be that all right. Now what we want to do is to look at that inequality that we have. So we have a M less than or equal to be in less than a week or two. See you. Let&#x27;s go ahead and subtract l because remember, what we want to do is we won&#x27;t be in to kind of be in the same form of what we have over here. The and minus l and C in mind. So we want to be in my cell to show up. So let&#x27;s go ahead and subtract l We get a n myself. Blessed are able to be in minus l Listen, I need to see in right now. So now, since Capital and is going to be the maximum and won it in two, we know that C and minus l will be less than Absalon because absolute value of this would at least be smaller than absolute. And so maybe I should see right here when Little Inn is strictly larger than capital in and also on the other side A and Maya&#x27;s l will be strictly greater than negative. Absolutely. So we can go ahead and actually read this as negative. Epsilon is strictly less than being minus l, which is strictly less than song. Let&#x27;s go ahead and like that, So negative up song is strictly less than being minus O, which is strictly less than absolute. And we could go ahead and take up the value of this or rewrite this as absolute value, I should say, and we get being minus l is strictly less than Epsilon, which is exactly what we wanted to show so you could go ahead and just stop there. But it&#x27;s always nice to kind of explain what you just showed at the end. So yeah, capital and is equal to the max. Oh, in one and into then when we have little in is strictly larger than capital end be in minus l will be less than epsilon and thus this is just the definition of convergence. You could go ahead and write the limit. As in approaches, Infinity of a M is equal to not a m e n bien is equal t. And then, since you finished a proof, you can put your nice little box and a little smiley face in it.

both here, um, seven states that if the Limited and Ezel and efforts continue settle, then the limit. So this is the statement of the pharaoh. The limit of f of a end as n goes to infinity equals f f l. So the proof for this is very short weaken, right. The limit as n goes to infinity half of an peoples f of the limit is n goes to infinity of a n Why can we do this Since efforts continue Asado This is just the definition of continuity at a point l now on. On the other hand, looking at the inside, we know that the limit of Anna&#x27;s cell So this justifies the final equation. So we started with the limit of f ve n. We ended up with a f of l. That was the claim that was to be proved. We have proved it. That&#x27;s our final answer.

The problem is proof. Former three us there in three. So the Formula Three off there in threes you hear after the you. It&#x27;s a cultural stuff from you. Plus after you from off here. We like you. It&#x27;s the country you want, You two. You&#x27;re three here. You want your to you three out of functions ofthe team? Then they did. I&#x27;ve found you. Yeah, this is off. You won off you two. After you three. This is equal to they seem a few one. Did he after you, too? Thank you. After you three, this&#x27;s equal Chu from You want last off? You want from me off from you two plus off You two from from you three plus new three problems.

here we have toe group Children 1.4. We use definition 1.3. For these proofs, the main point in each case is started. The desire. Equality holes for Raymond, some on. Then we can pass through the limit toe. Arrive at the integral. Let&#x27;s see f OPEC&#x27;s comma y and to your ex coma vile. Be integral over the regional. Healthy is a constant term. A four x coma by the A would be equals toe limit More B approaches to zero Sigma. I go from one to n see Time&#x27;s 1/4 you Wycombe a V a into their diet ai It would be equals two See into limit more be approaches Tau zero sigma I goes from Baldwin. I hope you like UMA v a data ai. It would be equals two. See into integral are a four x coma by be a They have proved most part off to room 1.4 In part two Let a four x comma y and G o X coma while be integrated all over the region are then we have double integral are a full egg school My wide plus Do you x school My wife be a how we can pass the limit toe arrive at the integral we get limit Be more than two zero sigma I goes from one to n I hope you Wycombe Avila There that ai mhm plus Dopp, Wycombe Avila into data in hell. We have applied dream and some now it would be equals Toe double integral are fo eggs Coma by D A plus the bell integral are do you fake school move I being hence proved Now we will use the most straightforward approach that easiest to understand and the easiest for a student to come up with. Unfortunately, they there are a couple of technical points that make this group messy. We have chosen, chosen to mostly ignored thes technical point in favor of understanding a partition. P off our gives partitions p one and p two off urban and are too even other Bangles off p on Intersect Urban. Similarly, for P two for notation, let us say that the first aimed rectangles on up even that will make it easier to refer right down you&#x27;ll be have double integral are F four eggs Goma y the hell a four x common bias integrate herbal over the region are now. We will use Raymond some and then we can pass to the limit to arrive at the integral Begin Limit more B A project to Zero Sigma where I go from one to N F O B y coma via There&#x27;s the AI. It would be equals to limit more Pay a protest to zero Break it sigma I goes from one to n f o p Y via they did not a last Sigma where I go from a plus one to end. Therefore few Wycombe Avila into Delta area. Whether we get limit more even a protest with you Sigma I goes from one to N i. Four v Wycombe Avila There is that a plus limit more p two approaches to zero Sigma. I goes from M plus one to win If you were a coma via there, Diane And finally we get double integral are one a four x com of idea plus the bell Integral are too a four x coma. Vile be therefore double integral f of X com of idea is equals through double integral Arvin F of X com of i d A plus double integral R two F, Opec&#x27;s comma by the hands full
