      Heck even my calculus prof watches RUclips videos because they explain better than the books, hence they can review better on RUclips

      @Illinium dumb ass that means if we get low marks we drop out of school then they lose profit that means they can't make money by making us dumber, and when a population is dumb then no job opportunities that means a lot are unemployed that means bad economy that means the government would never pay teachers to make us dumber because it would lead to bankruptcy then anarchy that means conspiracy theorist are drop out college students that also want others to drop out because they feel the more the merrier.

      @hotandsillycinnamonrollget6697 5 лет назад +4

      Mainly due to most universities now a days being an absolute bureaucratic unit. Classes are way too large and too fast. My teacher assigns homework that is extemly difficult and I usually have to look up the answer so I don't get decent practice. The questions on the test are different than the notes making the tests difficult. Here he explains everything we need to know not confined to a cirriculum. Tbh I think University is obsolete. Patrick's (and thenewbostons) videos proove this to me. I'm only in it because some executive in an office says I need a peice of paper to have a job.

    • @heavysaber9431
      @heavysaber9431 5 лет назад

      @@hotandsillycinnamonrollget6697 No they're not, you're not just studying hard. In college you have to study hard and if you can't keep up then that's your problem. Some universities even offer free tutorials, you have to utilize what's already at hand. Universities have entrance exams and if you passed it then you have to keep up with the standard.

    What I like I about your video compared to any of the other ones in youtube is..
    Your videos are SIMPLE, they have just the right amount of material and info..
    Nothing less and nothing more..
    And something to find out by oneself..
    :)
    I still don't understand why you weren't selected for the live tutoring program by youtube..
    Probably because of the low subscribers..
    You here that people starting spreading the message!!
    We need to get this guy and his channel KNOWN!!!

  • @patrickjmt
    @patrickjmt  14 лет назад

    @pssurfer7 yes, she was doing 'limits at infinity' - that is, when the independent variable (x) becomes arbitrarily large (goes to positive or negative infinity). The problems I do are often called infinite limits because the dependent variable (y) either goes to positive or negative infinity.

    @LowGhostRider 11 лет назад

    Patrick you could, like my teacher, refer to the denominator (what it will end up equaling) as a + or - SMIDGE. Meaning like if u have 5.001-5 you will have a + smidge when approaching from the right..so its (+) infinity since all numbers beyond 5 will create a + number

  • @brandonheath6246
    @brandonheath6246 Год назад

    When you calculate infinite limits, can you take the decimal of the x value and convert it to a fraction, and then can you leave your y value in fractional form? For example if you have to evaluate 5.5 can you convert to 55/10 and then do 6÷55/10 to get the fractional answer?

    @narleydude1 15 лет назад

    Hi. Um, I have a question. I solved your last example using CALCULUS SOLVED on my PC (math software). Anyway, I solved it and the answer came out as THE LIMIT DOES NOT EXIST. I understan the reason behind both answers (your's and the computer's) and how to get there. My question is this. If on my next test, I have to solve a limit like this one, what "road" should I take. Both answers make a lot of sense, and yet, they are completely diferent.
