Infinite limits (KristaKingMath)

Learn how to calculate an infinite limit. In order to determine whether or not the function has an infinite limit as x approaches a specific point, you'll need to first confirm that your function as a vertical asymptote and the point you're approaching. The function will have a vertical asymptote where it is undefined because the denominator of the function is equal to zero. Then you'll need to plug in values close to and on both sides of the number you're approaching. If the value of the function gets very large as you approach the vertical asymptote, then the limit is positive infinity. If the values get very large but negative as you approach the vertical asymptote, then the limit is negative infinity. Remember that infinite limits don't technically exist, but because it gives us so much more information about the function to say that the limit is positive of negative infinity, we'll often provide that answer instead of stating that the limit does not exist (DNE). If the one-sided limits are not equal, there is no general limit.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

great video!! if there was an award like "the best tutor award" then it must definitely come to u mam.. thank u lim(very->infinity) very much!!!!

[ThePinoyMamba]

Very clear. Well done. We need one more nine. But every one should understand that.
Thanks for another great video. Keep it coming. :)

This is close to the beginning of Calc 1 and part of what you'll learn when you study Limits & Continuity. Hope that helps, and good luck when you start taking Calc! :)

Ya, I noticed it after the fact, and didn't think it was too big of a deal. But I added an annotation there now, hopefully that helps. Thanks! :)

[kristakingmath]

I'm so glad! Good luck tomorrow!!! :D

[SidneyGutteridge]

thank you! i have a test tomorrow, this really helped :)

I really appreciate your videos. I am assembling quite the assortment of favored YouTube tutors for Calculus, but I find myself coming back to yours most often. I especially like how you are clear, informative, and concise. I just don't have the patience for a 35 minute video of something that can be explained in 7 minutes. This video in particular was wonderful. Kudos to you!

you have the voice of an angel haha first time taking calc so thank you this helped a lot! 

[faridizzat]

very helpful, thanks a lot, i gained a lot of understanding from your videos

[oranneecadena]

Great video, your voice is so soothing

[serenityshayanne]

I have been subscribed to ur channel ever since i watched my first video. i really love how short your videos are while still being very clear. A+ work : )

The day you can define the limits of a twister or the flanges of galaxy in their pathways in the universe, then you will be the next Einstein. Simply limits maths can never get there.

[davicorrea]

What's the name of the program you use? (love your videos)

[Money__Matters]

is it possible to solve this problem with the help of lopitals rule?

[brave]

Krista plz help me
what limit as x goes to 1 and the function is (1-square root of 1) /( x^2 - 1)
i found the answer by a limit calculator to be -0.25 
but how?? can someone explain how to do without calculator>???

[omarmartinez]

Omg I love you! Thank you Angel of Calculus lol

The universe will always have its mysteries and language and its in the stars. The problems are each pathways is différents in function of différents input and variables to which you want to reach. So that s why the rigid functions datas cannot ascertain those goals. And the dammed computer datas is to long to determine the right path if we can do another way to get there faster.by datas engineering. That's why the ivy school are somewhat out of dates because it's does not have internal control datas within the datas..

why have i been watching neck-beards teach me math this whole time

[chucho]

Your hot lol
Come teach at Elgin Community College! !
