How to Find the Limit at Infinity (NancyPi)

MIT grad shows how to find the limit as x approaches infinity or negative infinity. To skip ahead: 1) For a POLYNOMIAL or CONSTANT in the limit expression, skip to 1:56. 2) For a RATIONAL ("FRACTION") expression in the limit, skip to 8:49. 3) For something of the form (SINX)/X, skip to 23:01. and 4) For an EXPONENTIAL example, skip to 27:27. Nancy formerly of MathBFF explains the steps.

1) For a POLYNOMIAL or CONSTANT in the limit expression: the limit of a CONSTANT (just a finite number like 3), as x approaches infinity or negative infinity, will just be equal to that same constant number. For the limit of a POLYNOMIAL (such as 2x^2 + 2x + 5), as x approaches infinity or negative infinity, just focus on the leading term (highest x power term) in the polynomial, usually the first term. You can ignore all lower terms, because as x gets infinitely large (in either the positive or negative direction), the highest term is growing most quickly, and the lower terms will not affect the limit value. Then figure out whether this leading term will grow toward positive infinity or negative infinity, as x gets extremely large. For instance, if the leading term is 2x^2, as x goes to positive infinity, this leading term will also go toward positive infinity, and the limit will be positive infinity. If the leading term were -2x^2, the x^2 would go toward infinity, as x goes to infinity, but because of the -2, the limit is negative infinity. For X approaching NEGATIVE INFINITY, keep in mind that a negative number, to an even power, becomes positive. A negative number, to an odd power, stays negative. For instance, what if the leading term is 4x^3, and you want to find the limit as x goes to negative infinity? If you think of plugging in a very large negative number for x, the 4x^3 would still be large and negative because of the odd power. The term would go toward negative infinity, so you can write that the limit is equal to negative infinity.

2) For a RATIONAL ("FRACTION") expression in the limit: I show a shortcut (and also the official formal algebraic method) to find the limit, as x goes to infinity or negative infinity. For the SHORTCUT, there are three cases: 1) If the DEGREE OF THE NUMERATOR IS LESS THAN the degree of the denominator, then the limit is equal to zero, no matter if x is approaching positive infinity or negative infinity. 2) If the DEGREE OF THE NUMERATOR IS EQUAL TO the degree of the denominator, then the limit will be equal to the ratio of the coefficients of the leading terms of the numerator an denominator, no matter if x is approaching positive infinity or negative infinity. For instance, if you're finding the limit of the rational expression (2x^2 - 5x)/(8x^2 + 3x), as x tends toward infinity or negative infinity, the limit will be equal to the ratio 2/8, which simplifies to 1/4. The limit equals 1/4. 3) If the DEGREE OF THE NUMERATOR IS GREATER THAN the degree of the denominator, then the limit will be either infinity or negative infinity. For ex., to find the limit, as x approaches infinity, of (3x^2 - 2x)/(x + 5), instead focus on finding the limit of the ratio of leading terms, as x approaches infinity. So instead, you can find the limit of 3x^2/x, which simplifies to the limit of 3x, as x approaches infinity. Since 3x goes toward infinity, as x goes to infinity, the limit is infinity. NOTE: if x had instead been approaching negative infinity, the limit of the original expression would have been negative infinity, since 3x goes to neg. infinity as x tends to neg. infinity.

3) For something of the form (SIN X)/X: there is a trig property you can use to simplify: that the limit, as x approaches infinity or neg. infinity, of (sin x)/x is equal to 0. If your expression isn't exactly (sin x)/x but instead has something like 2x or 3x inside the sine function, like sin(3x) over x, you can use the same property but first have to rearrange the expression in a way that matches what you need. Be careful not to confuse this property with another, very similar, (sin x)/x expression for when x is approaching 0. That property states that the limit of (sin x)/x, as x approaches 0, is equal to 1. Check out my video on how to find the limit, at a finite value, for how to use that property.

4) For an EXPONENTIAL in your limit expression (with a negative power): for instance, if you are finding the limit, as x approaches infinity, of e^(-2x), first rewrite the expression using the reciprocal instead of the negative power, so 1/e^(2x). Then it is easier to see what happens as x gets extremely large and goes toward infinity. The e^(2x) gets extremely large, so 1 over a very large number will head toward zero, and the limit will be equal to 0.

    what if u have( 0/0 )or (Infinity/Infinity )or (-Infinity+Infinity ) ??????????????

    • Naweed Babakarkhail 4 years ago

      0/0 is indeterminate means that limit doesn’t exist or you didn’t simplify enough. Infinity/Infinity is simply 1 and -infinity+infinity should be 0 I believe but you also have to make sure that you account for the coefficients in front of x

To KNOW anything back then, you had to subscribe to some Specialty Magazine (Mathematics Magazine) or join a club. But, yeah, you just couldn’t Google anything back then. You knew or or you didn’t… researching anything was like climbing Mount Everest without a sherpa.

  • Chalen Yee 3 years ago

    Did she learn to read and write backwards just for the sake of making convenient videos for us?

    • Leo Volont 3 years ago

      We went over that in another video and some really smart guy told us that she must be using the Video Editing Software to flip to mirror image so we can read what she is writing from behind the Glass.

    0(∞) is indeterminate

    • Leo Volont 3 years ago

      Hi Drin, you say “0(∞) is indeterminate”. Really? Do you have a proof for that. My intuition is that if you have A(B) and A is Zero and B is any magnitude, then the Product will be Zero. And Infinity is simply a Magnitude, that, yes, in indeterminate in itself, BUT we are really CERTAIN about Zero, aren’t we? It is a case where once we know that that A is zero, the Product is already Determined and we can ignore the Value of B. Doesn’t that sound right to you?

    • Drin Koron 3 years ago

      @Leo Volont We know that 1/0=infinity so 0*(1/0) = 0/0 (0/0 – indeterminate)

  • MrMrREmm 3 years ago

    So for rational expressions limits to infinity are the horizontal asymptotes?! 🤯🤯🤯

    • Leo Volont 3 years ago

      Hi MrREmm, You say “So for rational expressions limits to infinity are the horizontal asymptotes?! ” Well, almost. If the Denom is a higher power than the Numerator then the horizontal asymptotes will be at Y = 0. If the Num and Denom powers are the same, then the Horz Asymptotes will be at the Fraction described by the leading coefficients. But if the Rational Expression is TOP Heavy, that is, if the Num out powers the Denom then you WON’T get a Horizontal Asymptote. There you have to Simplify your Leading Terms of both the Num and Denom and see what kind of Waveform that gives you (if the difference between the Powers is 1, you will get a Straight Line with a Slope, if the difference is 2, you will get a Parabola, etc.)

    How can you write?

    • Leo Volont 3 years ago

      Hi Piseth, you asked “How can you write?”. Well, we discussed it another one of her videos and decided that she write from behind the glass but then uses the Video Editing Software to flip it to Mirror Image. That would sound about right. Oh, when doing Selfie Videos, always check to see whether you look better natural or in mirror image… there is a difference. For instance, all of Tom Cruise’s movies are shot in mirror image because he thinks he naturally looks short and ugly.

      You can do the Mirror Image with just the Photo Video Editing Software. A lot of people use it because they think their facial symmetry looks better in mirror image.

  • Leo Volont 3 years ago

    Hi Nancy, I learned something today about your name. I was putting off studying Math (its summer break and next semester is Calculus I, but I’m using you to get a grip on both Calculus I and Calculus II). But, yeah, I was reading one of the most famous Novels in the English Language: “Clarissa” by Samuel Richardson, a novel written in the form of Letters going back and forth between the main characters. Well, Clarissa’s (Clary’s) best friend is Anna Howe, but whenever Anna gets particularly ‘saucy’ the name was becoming ‘Nancy’ which was a kind of a WTF moment for me because, you know, where did this Nancy just come from. So I looked it up and it turns out that Nancy was the diminutive form of Anna and only started to be used as a proper name in the 18th Century… so the change was happening even while this fictional Anna Howe was both Anna, formally, and Nancy, when she was being ‘saucy’. Cool, huh?

      Right handed, normally, on glass facing a camera on the other side. Then just flip left/right like a lot of webcams do anyway. The fade-out effect of just the text is a little more complicated but I figure out at least one way she might be using.

    • Xiang Li 3 years ago

      than another function? Well if the two functions are equal then they grow at the same rate. For faster or slower it’ll depend on what x is approaching or what the function is, I think.

  • Don't Mind Me 3 years ago

    17:50 When I use a graphing calculator to graph the function (3x^2 – 2x) / (x + 5) a vertical asymptote prevents the graph from approaching -5 so the limit of that function as x approach -inf must be -5?

    • Clemente Acevedo 2 years ago

      that -5 is not included because if you use it, you would be dividing by 0, and you can´t do that. The answer to a limit represents a Y value not a X value.

    thank you so much this video so helpful ,but i have confused about infinity times zero how is equal zero ,and we know this quantity is undefined

    • Jared Burgon 3 years ago

      I don’t know if this will help, but when I first learned about multiplication, I was taught as a number (a) and however many groups of that number (b). So 5 times 4 would be 5 groups of 4 (or 4 groups of 5). I think of it the same way with infinity and 0. You either have unlimited groups of 0, which is still going to equal 0, since there is never any value. Or, you could have 0 groups of infinity, in which 0 groups of something just equates to 0. Hopefully this helps!

    Hey! Thank you for a very helpful video. I was just wondering how the limit of x*[(sinx^2)/x^2] as x approaches infinity would be 0. The expression simplifies to infinity * 0, which is undefined. So would the limit not exist?

    • Sepums 3 years ago

      Anything times zero will become zero. Approaching infinity is like a huge number, and a huge number times zero is zero. The expression might simplify to infinity * 0 but the denominator is still 1 so it isn’t undefined, it’s just zero over one, which is zero.
