  • I work through 6 examples of finding the limit of a function as "x" approaches "a"...though at the start I state that I am doing 4:\ Four of these examples involve quotients where the function may be undefined at "a". EXAMPLES AT 2:23 3:20 6:05 8:23 13:40 18:59

    Thank you again for this video. I just started my calculus class. I put it off so long because I had to relearn all of high school and college pre-reqs that I already had credit for and now it is my senior year so I can't put it off any more. :-) You saved me THOUSANDS of dollars! My online calculus class has NO LECTURE VIDEOS! omg! I am expected to learn straight from a book. You are a lifesaver!

    Mr. Tarrou, Your videos are the best!! It has been 15 years since I took a math class so needless to say I was lost when I walked into precalc last semester. With the help of your videos I sailed through that class with an A. I'm on to Calc I this summer and I honestly don't know what I would do without these videos. Your lessons are a HUGE help here in NC!! Thank you so much!!!

  • @profrobbob
    @profrobbob  11 лет назад

    It is always a very good idea to start with finding the domain of the functions you are working with. For these questions I am only asking for the limit as x approach a constant, so I would not require my students to give the domain of the function as well. The fact that the second example is undefined at -1 shows that the limit does not have to equal the functions value at that point.

Unfortunately most schools are not as lucky to have outstanding teachers like you so it is very much appreciated that you take your time to do these videos to help students actually learn whats going on behind the scenes of the concepts and formulas. Most of us are majoring in some sort of science and engineering program so this will help us for the rest of our lives.. Again, Thank YOU So Much!!

    Thank you so much for addressing quotients. My teacher and videos on youtube only do the simple problems that of course I know how to approach. But no one ever takes the time to work out the harder problems-which of course because they're harder is actually what students need help on. This has helped me so very much.

    Like many other students out there, I like to thank you for taking your personal time out and making these videos. Your lectures and examples have been tremendous help through out my math classes. I am stepping into the calculus world next semester, knowing that you have calculus lectures and examples I am at ease.
    Not sure why many teachers do not take their time out and help students to understand the materials like you have been doing. I guess this is why it makes you unique and your work speaks for itself. I can go on and on about teachers, anyways thank you so much, and hopefully you continue to make videos. BAM go make more videos :)!

I have been very busy relearning my old Calc skills, working through my textbook, planning, and making Calc videos. I am also teaching three other math subjects this year, so I apologize for my slow reply. I have not relearned l'Hospital's Rule yet and taught it to my class. The AP Calculus AB curriculum does not require that I teach it, and it is in a later chapter of my Calculus book. Because of your suggestion...and others...I do plan on covering this before the AP exams.

    You may want to watch my video Infinite Limits and Vertical Asymptotes. The short answer is yes, if the function approaches Infiniti from the both sides of a. You are saying that the is no real limit when you state the limit is infinity.

  • @profrobbob
    @profrobbob  11 лет назад

    8-(x+8) is 8-1*(x+8) so you multiply the -1 through the parenthesis and get 8-x-8 and then that simplifies to -x+8-8 which is -x. I hope this helps and thank you for watching:)

    Sir,
    I can't find any videos anywhere for what I'm doing, which is addition & subtraction of limits. These practice quizzes I'm doing show a graph with curves that end up at 2 different points on both. It'll ask what's fx-gx. I'm realizing the connect the dots game and can follow the instructions asked, subtract. When I'm asked to add, the answer comes out being DNE. The question didn't ask if something exists or not, so why is that the answer??

    I have more of a question than a comment... Can you have a limit of a function as x approaches some value at infinity? what I mean is it possible to say that: Lim x->a f(x) = ∞, or is that wrong

  • @amakanzeadibe1732

    in the third example, where you divide by 8(0+8), wouldn't the denominator then be 64?

  • @ライアン-b1d
    @ライアン-b1d 11 лет назад

    I have a question. Don't we have to mention that x is not equal to 3/2 for the first question and x=-1 for the second question at 8:34?

  • @javeriasiddiqui4232

    Isn't the answer to the one at 18:41 supposed to be -1/64? Since its -1/(8*8)?
